I have an existing setup that works just fine, but need to upgrade to devices that support 1G interfaces to take advantage of an upgraded Internet speed (150Mb/s). The existing network looks like this. Internet<—>CM400<—>WGR614v9<—subnet A—>layer-3 switch<—subnet B Devices on subnet A and subnet B can both comunicate with each other and with the internet. A static route exists on the WGR614v9 to route traffic to subnet B via the layer-3 switch. A default static route to the WGR614v9 exists on the layer-3 switch. I'm trying to replace the WGR614v9 with a FVS318Gv2. I'm not using VPNs. I only need the functionality that existed in the WGR614v9. The new configuration looks like this. Internet<—>CM400<—>FVS318Gv2<—subnet A—>layer-3 switch<—subnet B A static route was added to the FVS318Gv2 for subnet B. Devices on subnet A and subnet B can communicate withe each other and devices on subnet A can communicate with the internet. But devices on subnet B cannot communicate with the internet. There is however, limited communications i.e devices on subnet B can nslookup, ping and traceroute to the internet but no connection oriented communications such as http, ssh, scp, apt-get, etc. It's like there is an implicit (either in-bound or out-bound) firewall rule for non-local (to the FVS318Gv2) subnets. Tech support says it should work. I'm wondering if anyone here has a similar setup or has similar issues.

The solution to my problem was to send the FVS318Gv2 back to Amazon and load opensource firmware (shibby tomato) on my WNR3500Lv2.

FVS318Gv2 - Not NAT routing non-local subnet traffic to internet

I have an existing setup that works just fine, but need to upgrade to devices that support 1G interfaces to take advantage of an upgraded Internet speed (150Mb/s). The existing network looks like this.

Internet<—>CM400<—>WGR614v9<—subnet A—>layer-3 switch<—subnet B

Devices on subnet A and subnet B can both comunicate with each other and with the internet. A static route exists on the WGR614v9 to route traffic to subnet B via the layer-3 switch. A default static route to the WGR614v9 exists on the layer-3 switch.

I'm trying to replace the WGR614v9 with a FVS318Gv2. I'm not using VPNs. I only need the functionality that existed in the WGR614v9. The new configuration looks like this.

Internet<—>CM400<—>FVS318Gv2<—subnet A—>layer-3 switch<—subnet B

Hi synoptics,

There shouldn't be a problem with this setup. Would you mind if you will create two VLANs on the FVS318Gv2 on different subnets instead?

Kind regards,

  That's not practical in my network. The FVS318Gv2 is in a wiring closet on the other side of the building of where the layer-3 switch (connecting to the cluster of servers) reside. It is also two layer-2 switch hops away.

    Hi synoptics,
    
    Kindly answer the questions below:
    
    a. Since there is a static route on the FVS318Gv2 going to subnet B, have you configured a default route for subnet B to access the internet?
    
    b. Is the Layer 3 switch directly connected to the FVS318Gv2? It would be best if you post a screenshot of your detailed network diagram on how is everything connected.
    
    c. Are there any Access Control Lists configured on the Layer 3 switch? If yes, kindly try to disable it then check if there will be internet access for both subnet A and B.
    
    d. Since you will just replace the WGR614v9 with an FVS318Gv2, have you tried to perform a factory reset on the FVS318Gv2 then reconfigure it from scratch?
    
    I look forward to your response.
