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.

Vmware connection with Networking and Storage

c
on the above Diagram, I have represented the Vmware Infrastructure in regards to its connections with Networking and Storage..
This is approximate representation of the infrastructure. Please correct me where I am wrong.

All ESX hosts have 2 Physical Adapters each connected to different Network Switches and each Physical Adapter is in separate VLAN.

Switch 1 and Switch 2 have 2 ports Trunked to separte Routers, Router 1 and Router 2.

Routers can have HSRP configured for Redundancy.

Router 1 and Router 2 have each 2 Trunk connections to 2 separate switches Switch 3 and Switch 4.

ISCS Storage has 2 separate connections (Separate VLANs) to Switch 3 and Switch 4.

--- First, please let me know if this infrastructure makes sense or in real world it does not make sense

---How are the routers configured to route Vlans Traffic coming from ESX Hosts towards the Storage and how are configured to route traffic coming from ISCSI storage towards ESX Hosts. ?

I am attaching the Diagram File, and feel free to modify it to the right representation

Thank you

Cisco Native VLANs

I would like to now if  I have few switches that are configured with default Native VLAN 1 and few with Native Vlan 60
will the traffic still go through both native VLANs  without L3 Routing?


Thank you

I have a point to point circuit between 2 locations...  Looking for a failover solution.

I have analog circuits at both locations as well as internet.

I used to have a couple of CISCO routers - but kind of sort-of worked.

I have a customer who received a CIDR block of IP’s to add to their SonicWall. They have a single IP that is currently used as the WAN IP. I need to configure the SonicWall to utilize this new CIDR IP range along with the current WAN. I want the internal computers to be “seen” as one of the CIDR IP addresses that will be assigned to it or via NAT. I was able to get it configured as a DMZ however the computers in the DMZ all appeared to the internet as the WAN IP address. I want them to appear as each individual CIDR IP. I would prefer to utilize NAT and have these new CIDR IP’s routed to the current 192.168.1.xxx range however I could also utilize the DMZ and have these computers assigned their own CIDR IPs.

The IP’s are similar, but different ranges and subnets:

IP for the WAN is 98.189.xxx.xxx / Mask: 255.255.255.128

They have a new CIDR block with this setup. The xxx in the CIDR are NOT the same as the WAN single IP above.
Subnet: 98.189.xxx.64/26
NetMask: 255.255.255.192
Suggested Default Gateway: 98.189.xxx.65
First Useable: 98.189.xxx.66
Last Useable: 98.189.xxx.126
Broadcast: 98.189.xxx.127

I have come across a few different similar suggestions however I’m sure I am not doing something correctly as none of these have worked for me.

We are looking into purchasing a replacement NAS for home.  My wife wants to get one that is less noisy than the QNAP TS-451+ 4 bay one we currently have.  I know that the disks are the noisiest part of any NAS, I can't really afford SSDs though, especially since I have currently used 8tb of space (RAID 5).  I was looking at the models of the Synology with 4-5 bays, NVMe slots for cache and are easily expandable.  Synology said that the only easy way to move my data to their NAS from the QNAP would be to have both up and running and map both as drives on a window computer and then copy all data from one to the other.

I guess my question is many-fold:
  • What is the best Quietest NAS (including the disks)?
  • What is the easiest way to transfer the files from one to the other?
  • Is there any way to do this that won't cost me an arm and a leg?

Just to be clear - this is because we are switching from a combination of Verizon FIOS and AT&T to Optimum Altice.  So the NAS has to be moved from its current location in my home office, into the living room because the Altice is a combined Cable box and Router.  If I could just connect via Wi-Fi, I could keep the current setup.

I started a list on amazon with new NAS devices in mind:

Hello Experts,

I am using a watchgaurd T70 and would like to set up two subnets on it. I would like to have the two subnets to have the ability to talk to each other as well. If anyone has information on how to do so, I would appreciate it.

Thank you

Senario:

Current topology is:

Cable Circuit/
Fiber  Circuit  ------>   Load Balancer (LAN1 port)---> WAN1 Fortigate 60d

Cradlepoint 4g   ---------------> WAN2 Fortigate 60d

I want to create a failover, so when both Internet Circuits are down on the WAN1 port, the Fortigate switches over to WAN2 for 1  specific vlan only.  I have created 2 static routes, one for WAN1 (default, priority1) and another for WAN2.  I have also created policy that allows for the specific VLAN traffic over WAN2.  

The issue is when both the Cable/Fiber circuit fail, the LAN1 port on the Load Balancer still shows active.  So, the Fortigate doesn't know the connection is down, and does not automatically fail over to the next route.  

When I try to setup a Performance SLA, it doesn't work because the Update static route action is only taken when the link shows Inactive.  

Could someone assist me with setting up a Health Link Monitor for 2 internet circuit public IPs, so when IPs are down on WAN1, the default route  will update to the 2nd priority static route?  Also, when the internet circuits come back online, the static route should update back to the default route.

I have the task of managing a venues internet needs.  This venue provides internet to shows that come in from time to time.  i have 1G internet on 1 pulbic IP.  When a request for internet comes in, i usually just assign them a vlan with the requested bandwidth speed.  There have been some instances where the client coming in request public IP address with desired bandwidth speeds.  My question, is what do i need to order from the ISP in order to distribute public IP's from my network.  I currently use Mikrotik Routers.

Hi All,

So, weird and frustrating problem with Windows 10 and Outlook 2016.
4 Sites, 1 central, 3 satellite.
The satellite sites are connected via Draytek 2862 routers.
Outlook on Windows 10 clients keeps popping SSL error randomly.
When checking Windows 10 is returning external wildcard IP for the domain name rather than the internal server IP of the Exchange Server.
Using nslookup connects and resolves the internal server every time, however looking up the exchange server name resolves to external wildcard IP.
Performing the same on a central site client returns the correct IP as the Outlook clients there have no issues with the pop up.
After a few minutes or a reboot the resolution returns to normal and resolves internally again.
The only DNS on the Windows 10 clients is the internal DNS server.
We have tried DNS forwarding on the Draytek but that does not work.
We have tried static IP and manual DNS on the clients but again no joy.
We cannot fathom why Windows 10 seems to completely ignore the internal DNS from time to time and resolve through external DNS servers?

Any help would be appreciated.

I have configured a Juniper EX switch with TACACSGUI.  I am currently logging in as a user and it is showing up in authentication and accounting reports.  Nothing is showing up in Authorization reports.

The tacplus enhanced-accounting option—(View the attribute values of a logged in user) is introduced in version 14.1.  The switch is currently running 12.3.  I am thinking upgrading to this OS will solve the issue.  

Can tacplus be implemented on a Juniper EX2200 switch running 12.3 with all AAA events successfully logged, including authorization?  Will adding the tacplus enhanced-accounting option solve the issue with authorization logging?

Hi,

We have an internet download speed of 10mb/s.

We have 10 Windows 10 PCs running 4K videos on our network.

Would this mean lower capacity or network speeds for our network?

Thanks,

SDN and SD WAN and SD Access and DNA Center

I have read about SDN and SD WAN.  if I understand They both are based on Centralized Control Plane.

So if I have  the Traditional Local Area Network  made up of Access/Distribution/Core   Layers,  and when I want to Implement SDN Technology , at what layer should I integrate SDN.
in other words if there is a hardware on which SDN is installed on, where should that hardware be located ?

SD WAN is WAN Technology , if I want to implement that technology  where should  I put the hardware that holds the SD WAN software.

if you can briefly give the    difference between SDN , SD-Access, SD WAN, DNA Center that might also help clear up the Terminology confusion.

THank you

I got a Comcast EDI connection with the usual two  sub nets /30 and the /27. I have a Meraki MX 100 with one Wan connection and I can assign one of the Lan port as a second WAN if needed. I setup the /30 as my main connection , internet works fine. I am not sure how to route /27 ones and using them as additional Public IP addresses because i need one for my VPN users. I know that the Meraki MX 100 has a VPN connection and it is being used and not to be used as different as it was setup. Simply how do I get to one of the /27 public IP.

I am not that familiar with routing on the Meraki MX 100.

Thank you.

I want to set up a server on my home network that will act like a commercial VPN service server would.   In other words, I want to send all requests through my home network and have the requests appear to come from me as if I am on my local LAN and WAN.

I have a  windows 10 computer I can dedicate as a server.  Is there any software out there that can make this happen.

I have a VPN router remotely that can take care of sending the requests.  I just need to know what to do on my home router and (forward ports) and on my home w10 machine to emulate the commercial services.

Any help is greatly appreciated.

I currently have two networks in two separate buildings. We will call then Network A and Network B.

Network A has a Unifi Security Gateway Pro and (3) Unifi AP-Pro’s. It is controlled by a local machine.

Network B has a Unifi Security Gateway Pro and (2) Unifi AP-Pro’s. It is controlled by a local machine.

What I would like to do is have both Network A and Network B controlled by the same controller. I have decided that I will use the local machine on Network A to control both networks.

Based on what I have learned I am required to change the Inform URL on all devices on Network B to point to the controller on Network A.

I installed the Chrome app called Ubiquiti Device Discovery Tool on the controller on Network B and did a scan. If found the Unifi Security Gateway Pro and (2) Unifi AP-Pro’s.

When trying to change the Inform URL for one of the Unifi AP-Pro’s to the controller on Network A I get a “login failed”.

I am using username: ubnt with password: ubnt. What credentials am I supposed to be using? I have also tried the controller login and network login for controller machine. Nothing works.

Yes I opened port 8080 on Network A and forwarded that port to the controller machine IP.

Hello,
I would like to know what are the ways to migrate catalyst 9k switches already running in the network and needs to be migrated to Cisco SDA.

Current setup:

All the switches in the network are migrated to Cisco 9K.  Cat9500 is a collapsed core switches and few IDFs with cat 9300.

We wants to migrate these devices to SDA where we have DNAc and ISE in the HQ. All the cat 9k switches are enabled with Advantage licenses.

Can anyone please with steps to migrate to Cisco SDA.

Hey Experts,

We have a Cisco RV430 Router with VPN capabilities. We are trying to set up the VPN on a Mac OS machine. It worked fine on Windows but the settings appear different on Mac OS. Any tips or links appreciated as well!

VOIP calls suffering from silent patches.

We had BT Cloud Voice put in around 6 months back and have suffered with issues since it was put in. We put this down to our FTTC lines, however we have now had a Virgin Leased Line installed (100mb/1gb).

We currently have around 90 computers and 90 phones. These are run through Netgear GS752TPv2 switches and to a Draytek 2926 router.

Looking on the router, the syslog is showing quite a lot of errors similar to the one below:

 [VoIP_QoS] VoIP RTP[45348] Rx Loss detected: 16/115 ...

There is also a few errors as below:
 [VoIP_QoS] VoIP RTP[45344] latency detected...220.

I'm assuming the first error is the receive packet loss (of around 15% in the case above) which could be causing the silent patches.

As well as this, I've setup a ping to the router from two different computers that are in different switches. They are both getting timeouts at the same time, one or twice a minute (sometimes there is a longer gap, sometimes there will be 2 within 10 seconds).

Any ideas where to start looking to try and resolve this issue?

Thanks, Shane

Hi all - I keep losing internet connection for 10-20 seconds, then it restores itself.   This happens about once or twice per hour.  By the time I start to test it, it's all fixed, so difficult to troubleshoot. Can anyone suggest how I might track down the culprit here?  Even just some SW that will tell me if I lost connection over the last 24 hours would help me troubleshoot things.  (Have already powered down cable modem, router, & restarted, reset modem, etc)

I have a basic setup, we use WiFi only, not sure if hard-wired Ethernet also goes out or if it is just a WiFi problem

Hi,

I have three Edgerouter X running site-to-site VPN (site a, b and c) .  Everything was working fine until the devices were restarted.  I've gone through all of the available troubleshooting and can't see to figure out why Site A and Site C cannot ping anything on Site B.  I've checked and double checked all of the configs and everything matches up.  I know that there are some known issues with version 2.0.6 so I'm running 1.10.10.  Do you have any ideas I can try?  Thanks!
