Dear All,

I would like to configure the connectivity on my home but I'm having some doubts and would like your help in order to configure the best way possible.

Devices:
Modem:  TPLink (TD-W8901N)
Router: Linksys (WRT1900ACS)

Currently I have two different options to configure internet connectivity:

1- Allow the TPLink to connect using PPoE on PV2 and specify user and password on the Modem and connect the cable from the TPLink to the internet connection on the Router Linksys (WRT1900ACS), so using this way we will receive internal IP Address from the TPLink instead of the WAN IP on the Internet Connection in the Linksys router.

2- Set the TPLink as Bridge Connection and connect the cable to the Internet Port on WRT1900ACS and configure the Router to connect using the PPoE on the Linksys and just use the TPLink as bridge.

Can you help me to understand the best recommended configuration and some explanation why just to understand?

Also would like to know if there any required configuration on the TPLink like VCI or VPI or something specific to have better performanc from the ISP?

I'm currently having performance issue on the connectivity and wanted to undertand the best way to setup the connectivity.

Thanks in advance,

What is SQL Server and how does it work?

The purpose of this paper is to provide you background on SQL Server. It’s your self-study guide for learning fundamentals. It includes both the history of SQL and its technical basics. Concepts and definitions will form the solid foundation of your future DBA expertise.

I am trying to implement a new network infrastructure.

Plan is to have an ASA 5508-X in our head office, and a number (starting with 4) ASA 5506-X devices in our small branch offices. Plan is to have the branch offices route all traffic via a VPN to the head office, so the 5506s just need to connect to a ISP, bring up a VPN tunnel, and maybe have a DCHP server or relay.  No filtering or examination of any traffic will occur on the branch office devices, this will all happen at head office. Also, the head office device wil be managed by an vFMC console, while I plan to just use the inbuilt GUI for the branch office devices. Since this is such a simple config, and the branch offices could cope with being down for a week, I did not order support for these devices.   Possibly a mistake. :(

All devices are running FTD 6.2.0.2-51, the latest.

Anyway, the issue I have is that I cannot get the ASA 5506-X devices to connect to an ISP. A couple of sites have ADSL connections with PPPoE. It looks like the ASA 5506-X does not have any sort of dialer, so it cannot be configured to authenticate. Seems a pretty basic feature to be missing, usually I would have just set the ADSL modem/router up to just be a modem, and used the firewall to authenticate.

Next attempt was to set up "Half bridge mode", (AKA RFC1483) on the ADSL modem, and let it authenticate an just give the ASA 5506-X the static IP via DHCP. I set up a modem to do this, plugged in a laptop, and it worked as …

I have two locations with almost duplicate setups.  
Location 1:  On a network run by a PDC.  The ISP is a cable company.   The one office in this location has 3 computers all connected to the network via a Netgear 5 port switch.  But also connected to this switch is a DSL connection via a dsl modem line to a preset location..  When the users need to connect to this dsl line they just click on the shortcut created on their desktop that directs them to the preset IP address.   All other communication for everything else goes through the regular PDC/cable network.  Using DHCP and automatically sees PDC as DNS provider.  Works great.

Location 2;  On a network but run just by a router, not a PDC,  through the local Cable company.  Two computers connected via an identical 5 port Netgear switch as in the location 1.  They have the the exact same dsl line via the same dsl modem connecting to the same IP address as in location 1.  The problem is that you can only connect to one or the other in location 2.  If you want to connect to the dsl location via the dsl modem, you have to disconnect the cable from the router from cable company at the Netgear switch.   Or if you want to  use cable you need to disconnect dsl modem from switch.  Also running DHCP and DNS being provided by either the DSL or cable depending on which you are using.  

What would cause one to work and the almost identical one won't?

I am trying to connect to a VPN using a Virgin Media and each time I try it states an error message. I was wondering if there is an settings within the router that need to be enabled/disabled? I would be grateful with any ideas. Thanks

Our customer has regular eircom (Irish Telco)  broadband in his residential house which comes with its own wireless router.

He wants to have wireless broadband in old farm yard out houses and sheds that surround his house. He already has live Ethernet cable & broadband in these out-houses.

He wants to know what is a high quality solution so that he can connect 3 or 4 central wireless access points around the various outhouses and sheds, so that he has also a Wireless/Wi-Fi solution which provides the strongest signal, and will hand off the signal from one to the other, so that he doesn't  lose his laptop connection as he moves through zones.

A high quality solution, where each AP doesn’t interfere with the next, and provides the strongest possible solution, and can hand off the signal to the next.

Thank you
Robbie.

Comcast EDI is setup and working with Layer 3 IP and gateway but need access to usable IP Ranges for external printing routing to internal printers, tried one to one nat but didn't seem to work?  Comcast engineers weren't very helpful, so I need the experts help

Hello,
we have a TZ-210 wireless that need to change a couple of things on.  

We are connected to a comcast business gateway device.  It has wireless and we use that as an outside wireless,  It is not setup to access the internal network.  When we setup a laptop of phone we use that for VPN testing and remote connectivity.  I have 2 issues.

1. I cannot connect to the management interface on the modem, it is the default 10.1.10.1.  It keeps getting dropped in the firewall.  What rukes do I add to tallow this?
2. We cannot send email from our mobile devices when connected to the Comcast wireless.  I would expect it to be a rule as well, but I'm not sure what to add to make this work.

We want to keep the comcast wireless off the internal network. But we need to access the management interface, plus some of the users need to be able to send via exchange when using devices or phones and sending exchange email.

Thanks.

Over the past few weeks my laptop has appeared to be non-responsive. Running speedtests shows the download speed is fine, but the upload will start strong, then the test just seems to hang. I've tried multiple browsers, uninstalled the antivirus, turned off the firewall and Bitdefender but nothing seems to help. Thinking it was the router, I ran a speedtest tethered to my phone, but similar results. Another laptop worked fine with the router as well.

I see no issues in event log, and I tried to update the wireless drivers but it was up to date. I'm not sure what my next step should be.

Thanks for any help.

I have 5 IP's assigned by AT&T to me on my On Demand Fiber circuit, but I only have 1 public address to the WAN. How do configure my 3 TZ300 to each use one of the assigned IP address and each to be a DHCP server?

I have an internet semi leased line purchased it for business purpose (250 Mbps).

I've recently purchased a new wireless router (Dlink-DIR-842) and placed it in office for internet access. Initially when i setup the wireless router, i was getting speed of 35Mb UP 32Mb Down when over the wireless. All of a sudden, the wireless has gotten very very slow and i see only 3 Mb up/1Mb down sometimes not even 2Mbps. But when i connect thru LAN, it give me damn good speed upto 75up/80down. As a workaround, I've tried changing the wireless channel from Auto to 6 and then to 11 but none of them has changed anything.

Confirmed that there is no issues with the line as it give almost near to what ISP has promised if i connect directly. Any suggestion for the wireless settings?


I presume the issue is with Router itself. Also, Dlink-DIR-842 doesn't have much settings options where i could look for some sort of troubleshooting.

Screenshots of the settings are attached for your reference.

Hello,

I am switching some of our broadband connection from ADSL to NBN and with that need to put a new modem into our existing infrastructure

We are going to use a Cisco 887VAW which is compatible with the NBN network with the correct firmware for these

Can someone please take a look at my Bridge Config as its a little different to my normal ADSL ones i use on the old routers as now has the vdsl interface

I think this is right but please let me know

I have put a Management IP on vlan11 FA3 as well so i can access the until via telnet

Has anyone worked with DSLAMs before?  If so, what manufacturer?  I currently am testing a DSLAM but not having much luck when not in bridging mode.  We must have our clients isolated from the modems and DSLAMs and can't use these devices just to pass through data traffic.

This is our current small office's setup:


Ciena 3930 fiber modem (provided by at&t)
ethernet cable connected to modem (port #2)
cable drop through ceiling --> office IT room
1 port switch converting cable into RJ45 IN

Connecting my laptop directly with an ethernet cable into this port, using the static IP provided by my ISP, I get my full bandwidth during speed tests (100mbps down/up)

Connect a router into the port (Apple Airport Extreme) --> connect via wifi to router
speed test shows ~15mbps down/ ~50mbps up

Connect via ethernet cable into router
speed test shows ~15mbps down / ~50mbps up

Thinking the router was having issues, I brought my Asus AC1900 from home, factory reset it, and set it up with the static IP, etc. and am getting the same results as from the Apple router.

As soon as the router is removed, I can get a full 100/100 connection directly to my laptop

Are there any compatibility issues with "enterprise grade" fiber modems and "consumer grade" routers that could be causing this?

If you would like any other information that might help, please let me know and I will update ASAP.

Thank you

Hi Everyone,

I'm having what I believe to be a DNS issue.
We recently moved our office and have a new ISP; Comcast. We have a new external static IP address and that seems to be working. We are able to send and receive Email without issue. Comcast has updated our rDNS so that's all set too.
The problem is accessing certain web sites. For example, Google comes up fine but when I try to access support.hp.com, the site never loads.
I have a ReadyNet WiFi router (provided by Comcast) between our internal network and the Comcast modem which is in pass through mode. The ReadyNet router is acting as our Gateway and for all intents and purposes is working as it should.
When I use nslookup from my workstation for www.google.com, I get 2 responses. The first is from our internal DNS server. Good. But the second, Non-authoritative answer is:
Name: www.google.com.<our internal domain name>  i.e: www.google.com.company.com
Address: <this is our old external static IP address> ?????

I'm at a loss as to how it can be returning our old external static IP. Where is it getting that from?
I have 3 servers. One is the DC the other is our Exchange server and finally, a secondary DC of sorts.
Both the DC's are running DNS. One DC is running Windows Server 2008 R2 Std. Ed. and the other is running Windows 2003 Std. Ed.
The funny thing is I can surf any website from the servers without issue. Of course, these all have static IP's, DNS IP's, etc.
However, if I do an nslookup …

Hi There,

The internet speed at work has become very slow for our users,
We have 100mbp speeds however, its taking more than 3 seconds to load a page up.
We have changed the DNS names server from Google DNS to Open DNS on our firewall, However, this
Has had little positive effect.

I have a small business network where I want to limit the bandwidth to each user, preferably being able to configure that in groups or via SSID where I could limit groups of users.  The current setup uses 2 separate unlinked BT Infinity FTTC lines with BT hub5 router where the users are split across both lines however on either line it only takes a few people to stream and the service clogs up. I'd like to be able to limit each person so if someone streams video it doesn't affect other users.  It would be nice to to be able to block sites such as youtube if I need to go down that route.  The network is not server based, merely laptops connected directly to the router with IP's assigned via DHCP.

Over the past year I have had intermittent but repeated problems with dropped internet connections. Oddly, it usually happens only on weekends when activity on my home network I believe is low. My internet provider tells me that it is a bandwidth issue. Specifically, they are telling me I am exceeding the upload capacity of my connection and that this is causing the connection to drop.   They tell me that this is commonly due to a cloud backup or similar condition.  I am not running a backup at that time and cannot figure out what is causing this issue.
- Is there an "easy" way to troubleshoot this?
- Is there a way to use my Sonicwall firewall to place limits on upload and prevent the connection from dropping?

Free Tool: Site Down Detector

Helpful to verify reports of your own downtime, or to double check a downed website you are trying to access.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

I have 2x ADSL connections and would like to merge both into one router with load and balance features.

1. First ADSL with BT (BT router provided)
2. Second ADSL with Plusnet (Plusnet router provider)
3. Both ADSL routers  will feed Cisco RV325 Dual-WAN Broadband VPN Router RV325-K9-G5 that supports dual WAN.

Will the following scenario work?

- Disable DHCP on both ADSL routers
- Enable DHCP on Cisco router only
- Set fixed IP for Cisco on both ADSL router
- For WLAN service I will connect a Time Capsule to Cisco router and also disable the DHCP on Time Capsule.

- How to deal with DNS servers for the DHCP server on Cisco router?
- Any considerations or advise to achieve/make this run properly?

Thanks,

Hi everyone,

Description of setup: Cisco ASA 5510 with a leased line and PPPOE connections, multiple internal LAN segments. Leased Line has a static IP and manual default route, PPPOE gets IP and Route through DHCP.

Problem: Only one route is added into the routing table, as such we cannot route traffic over the PPPOE connection as the ASA will always follow the default route in the routing table.

Scenario: We are migrating from an old 2Mb/s Leased Line circuit to a 1Gb/s PPPOE circuit, during this process we will need to utilise both connections on the same firewall. This is to allow us to provide a seamless transition for our users and customers with minimal impact to business services. Our aim is to begin changing external services to point toward the new IP on the PPPOE circuit and change the NAT statements on our firewall accordingly. Eventually all services and users will be migrated over to PPPOE and the Leased Line will be removed. Unfortunately a cut-over migration is not feasible as we have hundreds of services that would need to be migrated simultaneously.

Ideal solution: To be able to send and receive traffic through both WAN connections at the same time

Any help is greatly appreciated, please see below the show version from our existing firewall (to be replaced with a 5525 after the migration):

A few time now using a Cisco ASA5506X to dial out with PPPoE has failed and haven't managed ot get to the bottom of it. I know PPPoE works on the line because I can hook my laptop directly using a ADSL/VDSL modem, use the right details and I get connected.

Running a debug on the ASA and I get the following, I have asked the ISP what Optino 19 is referring to but if anyone has any other thoughts on what may be the issue or where to start looking I would be grateful.

We have a fiber connection between two buildings approximately 400' apart that is not currently being used, but we would like to connect the two buildings to share resources between the two. Both buildings have the interface connection in the attached picture. I've never worked with fiber before, so I need some guidance on how to connect both LAN's.  I have a Dell SonicWall NSA2600 in the main building and see that I can add a module to the firewall where I could connect the fiber.  Would this be a SFP module and would I need what's called a short haul module?  The secondary building would just have a switch to connect the client equipment to.  I have a Dell 2824 that has 2 SFP connections on it and wonder if that is the right interface to go directly from the fiber cable on the Leviton box.
Thanks!

I have just started working at a company as IT manager about a month ago.  They currently get all internet and phone lines via TalkTalk.  My experience of TalkTalk has always been bad and it seems like not much has changed.  Account managers who don't respond to emails, no web portal to track orders, current services, billing etc.  Very slow providing new services (I am aware some of this responsibility lies with Openreach) but TalkTalk appear to be very disorganised as a company which adds to delays.  I am also ruling out BT Business on the count that unless you are a FTSE100 company, they are just too big to care about you and adopt a like it or lump it attitude to any problems.
We are due to move head office in the summer and I am looking for a new ISP and telecom provider.  
We have a head office with approx 50 people and another 12 sites with about another 50 people spread among them.  
Currently we have a 10Mbs EFM connection and ADSL backup at head office for internet and 10 channels of ISDN30 for phones.  I will be looking to upgrade this to a leased line fiber connection probably at 50Mbs.
The sites have EoFTTC connections where available or ADSL annex M if not.  A lot of the sites are tied into contracts, so I am mainly looking for head office to start with.
I am basically looking for recommendations for a good ISP with customer service and reliable connections who are also good at dealing with BT Openreach.  They also need to support VoIP / SIP connections as…
