I have an Actiontec GT701D DSL Router and a Linksys EA3500 router. The Actiontec router only has one ethernet port so the Linksys router works as the AP for all computers on the network. I have a server connected to the Linksys that wants to accept connections from the internet, but nothing seems to be able to connect to it. (It can access the internet just fine). But computers within the same subnet are able to connect to it. The Actiontec set the Linksys as a DMZ and the Linksys is forwarding the appropriate ports to the server, which has a reserved/static IP via DHCP.
Actiontec - WAN IP: ISP provided, Subnet: 192.168.0.X
Linksys - WAN IP: 192.168.0.2, Subnet 192.168.1.X
Server - WAN IP: 192.168.1.103
I am pretty convinced that this is an issue with routing tables, but whenever I try creating a new entry on the Actiontec router nothing shows up on the Routing Table.. which leads me to believe my entry is wrong or there is something wrong with the firmware, probably the former. How should I configure static/dynamic routing and NAT on either the Actiontec or Linksys router so that connections from the internet make it through to the server on the linksys subnet? Port scans show 0 open ports, which I know can't be right.
