A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

I need to  allow the following ip ranges through the draytek router/firewall to allow Worldpay to scan our network to ensure it meets PCI compliance.

91.209.196.32/28
178.255.82.64/27
199.66.200.32/28

Can someone ecplain how I would do this. I have created 3 objects matching the above subnets but Im unsure what to do next.

So heres the setup

I have a new open mesh POE switch I'm trying to plug into existing 2960 so that we can plug in some OM AP's to it.  I can plug in the OMS8 switch into the cisco with the cisco switchport in access mode for the vlan we want it on. I can run a IP scan and see that the switch indeed gets a DHCP lease, i can go to that ip in browser and get the admin interface (not allowed to log in ). But the switch never checks in with cloudtrax.  I have 4 other AP's on the same subnet that check in fine, so i don't think content filtering  (as suggested by their support) is the issue, though they say the switches check into different servers than APS.  So heres the setup

OMS8------>2960----->3650------->5515ASA

is there a way i can search for that mac on either the 3650 or the ASA to see if its getting filtered?

Hi Guys,

We have an IP block from the ISP
Thus a couple of public IP's assigned, example:
196.31.231.80
196.31.231.81
196.31.231.82

Our NAT policies on 196.31.231.80 over X1 interface is working well.

I've been trying to setup additional NAT policies on 196.31.231.81, but experiencing a connection issue.
Which brings me to the following questions:

1.  Is it necessary to setup a Virtual Interface for 196.31.231.82 on X1?
(255.255.255.0)
Or could the NAT rules simply refer to X1?

2.  I tried setting up a Virtual Interface on X1 for 196.31.231.82, but it complains about the same subnet used,
What should the subnet for the Virtual Interface be?

Hi Any one can explain two terms? -- "Cisco Rolled X1" and "Cisco Straight X2"
The Straight means straight cable?  Thank you
Here is where i got the two terms:

Hi Guys,

Our SonicWALL TZ400 recently only shows the outbound and loop-back rules.
The Inbound rules are no longer displayed on the Firewall / Access Rules page.

I believe this could just a setting?  It doesn't show all the rules even after selecting "Load All" ...

Topology is like this: N7K1 ----- N5K1 -----Opengear1(OG1). HSRP ip: 10.2.0.1 in N7K1, which is connected(through N5K1) to OG1, 10.2.0.11. N5K1 is layer2 there. N7K1 can ping OG1 with 97% successful rate. What can cause ping loss?  We also have N7K2---- N5K2 -----OG2. but it can work well without any issue. Thank you

Hi We can access the device Opengear by https, but cannot ping it. ACL might be a reason. In addition to ACL, any thing else can cause the issue? Thank you

Hello, I have a Verizon Fios G1100 router, the reset button was hit yesterday so I had to reconfigure the wifi so I create the main SSID and a Guest SSID. On the main wifi, SSID the 2.4Ghz and 5Hz SSID are the same names using WPA2/WPA mixed mode and the guest account. The problem I am having is when users with their laptops trying to connect it takes forever for the connection to complete most users will just give up. My desktop users with older systems are connecting without any problems so this morning I renamed the guest account and removed the password and the laptop users could connect but it still took a fair amount of time for the connection to complete sometimes we would have to reboot and turn the wifi on and off.  Any direction on what I am doing wrong or settings that are not set right?
0
Will it cause any harm if I setup two wifi routers (not AP connecting to a central controller) in my office, same SSID number and password but in different channel ?

Two wifi will be placed in each end in the office and in a user laptop travel from one end to another end, it will also get connected to the wifi.

Thx

Hi Here is Opengear IM4216. I could not find relative document on it. Is it layer2 or layer3 device? What kind of device is it? Thank you

I have 2 routers in my home: in the basement i have my main Verizon Fios router and i installed another Trendnet router on the 1st floor which is wired to the main router by a patch cable. i have ipads, iphones and an nexus 6 smartphone which runs Android.
i don't get reliable internet connections on any device and a lot of times it just disconnects altogether.
i think it has to do with security settings on the routers. i don't know which ones to use. i just want a good connection.
can anyone recommend routers security levels so that all devices work?
thank you

Trying to make sure I have created and assigned all new IP address and what they are assigned to on my internal Home Office.  IF I can print out the MAC Address for TV and ROKU devices and see the names of the machines on my network. I assume the IP addresses will be fairly easy to list so that I can create a simple log file of who is who and what is what so to speak. How would I do that and or what would I do?

I recently installed a Cisco 1921 router as the def gateway for my network. I also have a Cisco ASA5505 9.2 on the LAN behind the router. My goal is to allow AnyConnect Client SSL, Clientless SSL and site to site VPN passthrough on the router. So far I had a chance to test Client SSL and Clientless SSL and my router configuration does not seem to be working. From the LAN I can establish a VPN session to the outside interface of the ASA. Can you please review my configuration and point me in the right direction?

Hello,

I am trying to research this question but not getting any concrete answers. I have multiple hub locations (none MPLS) connected to HQ via DMVPN. My bandwidth circuits at those external locations varies between 5Mb up to 100,Mb. My questions is, with SD-WAN, those sites with only 5Mb, will they see performance increase? Will I be able to manage this bandwidth? Or will I be cancelling the circuit with.. let's say Comcast and get a SD-WAN provider and thus leverage the speed? Also, if thats the case, will I be signing up for certain speed with the SD-WAN provider or no?

My Cisco Router is 3 years outside its last firmware update. I am having problems with it so I purchased the Asus AC3100 above. It has 8 LAN ports and a powerful wireless connection with 5 Ghtz. It has 5 Ghtz and 2.4 Ghtz as well as 8 LAN ports. Not worried about the LAN ports just need to figure out how to configure the router so everything below has its on dedicated IP address. ( I assume that is what I need to do?) I assume this but not sure how to do. If I am leaving something out you need or I need to do please advise?

The Problem is when I start to run specific machines or watch TV intermittently, I get conflicts and dropped signal all over. The only way to resolve with the old router is to shut down and reboot to figure out what I can keep on or leave off. I hope this Newer 2017 ASUS Router will be more helpful and last at least a few years. Listed below is what I have in my home/office. Can anyone suggest any configurations or practices that I can use to get this working? I have listed below information as well as device connection types. 1W = One wireless device. 1LAN = One LAN (hardwired) connection or both. Any advice on what I need to make sure I do to allow everything to be seamless is appreciated. Thank you.

I have wireless devices all over the house.

I am trying to understand the effect of configuring  ip summary-address rip 0.0.0.0 0.0.0.0  on the Hub router in DMVPN Network.
per the  book, Spokes should see in their routing tables the RIP default Route 0.0.0.0, but it is not the case in my LAB

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

We have a connection to the Internet and now we just added another Internet connection. We want to use the new Internet connection just for Office 365. I am not sure how to go about doing this as I have a default route from my core to the FW and then from the FW to the provider router. So currently all Internet connection, including O365, is pointed to the default route and there is nothing going out of the the new Internet connection.
We have a physical connection from the provider to the FW, then from the FW to the core switch.

Any thoughts? Thanks

I currently have a SonicWALL TZ 200 configured with WAN connections on 2 interfaces. I recently purchased a HughesNET satellite connection and I want hook this up to the SonicWALL (And add it to the failover/load balancing). However, once I received the Modem from HughesNET (HT2000) I learned that it does not have a "Bridge" mode built into the router. I cannot disrupt my current Subnet (needs to stay the same). Does anyone know if there a way to configure the interface for the modem/router combo into the SonicWALL so it will work properly?

Thanks in advance.

If a router run a BGP with neighbors, will it use the BGP Path attributes and Best-Path algoritm to determine the best route to particular network and then put it into routing table ?  Or, does the router only check its BGP routing table only and decide which path to go for a particular network ?

Thx

Intro

I would like to setup my personal firewall directly to the Netgear DM200 ADSL Modem (in modem mode).

This would allow me to connect directly through VPN to my work ASA5510.

Setup

ADSL Phone line <-> ADSL filter/splitter <-> Netgear DM200 <-> ASA5505 <->BT HomeHub5

I have set the DM200 in modem mode with the username "bthomehub@btbroadband.com", i dont know the password or the Authentication method "PAP or CHAP or MSCHAP"

The ASA is also asking for an VPDN group which I have no details for....

The DM200 is working because I can access th einternet when connected to the LAN port when in Modem mode.

Issue

Ultimately i just want to securely VPN into my work ASA but it would be useful to implement the Firewall for all outgoing internet traffic instead of placing it behind the BT Homehub5 that im replacing .

I would really appreciate it if anybody could offer any advice or help.

I configure 3 routers in a line each with their own addresses and loopbacks. I then create bgp neighborship between them and advertise their loopbacks. I can ping from R1 to R2's loopback or R2 to R3's loopback but I am unable to ping from R3 to R1's loopback.

Did I miss some configuration or is that just how it is by nature?

Thanks!

I'm troubleshooting a slow connection to my home office.

Pinging the domain controller returns 92 ms.

Is this too high?  What is the normal return in ms?

I am connected to the home office via MPLS circuit.
