Classical Routing - Assistance needed
I am trying to get routing mode (Note: not NAT mode) working through my Netgear Firewall. It's an FVS336G v2. I have the following CIDR Block and IP Address from my ISP - COX. My block is as follo...
Never mind about the ip addresses - I'm starting to think the gateway on the ISP side (57.224.xxx.97 maybe incorrectly configured.
When pinged from the router itself it responds, because it is being pinged from a host on a network that is directly attached, but when pinged within from your network it does not know where to send the reply (back to your router) and maybe sending it forward to it's own default gateway.
Do you mean that COX does not know to send the packet back to my netgear or to my cable modem?
Do you have the facilities to connect a sniffer to the WAN interface of the FVS336G? Either a network tap or an old hub (if you can find one) and a laptop running wireshark would let you see the traffic to confirm if the gateway at .97 is responding.
I do have the captures from the WAN side of the firewall, those are done in the diagnostics page. I do not have a HUB and no TAPs so i cant do more than that.
