Modem/Router/Ports Major long Term Issue

by SpinyGloomz - 1/2/13 6:07 AM

Okay so this is an issue which i gave up on about a year ago. I used to run a multitude of servers from home computers (such as minecraft servers) and the issue i am running into is now i can not.

Almost a year ago i moved houses obtained a new internet plan and a new Modem (i am not sure of the names of the newer versions which have inbuilt routers and wireless capabilities, but this is one of them). When i connect directly to this Modem i can port forward and my ports are found to be open when using a port checkers. The the next part is where i ran into some issues, i run two computers and an Xbox and wireless is pretty much out of the question seeing as i have a foot thick concrete wall which blocks any to all signals form traveling through. To work around this i run one hugely long cable to a older router (Cisco Linskey E-2500) and connect my xbox and computers with individual cables. The issue is now that i have both a modem(routerthingo) and a secondary router which acts as a switch, i can no longer port forward in a way that anything can connect to my PC. When testing with external Ip address its comes up as closed. i attempted to open the port on the primary router for both my computer ip and secondary router ip, i then went on to open the port on my secondry router think that it was just like have two doors which needed to be opened. none of this work and i really would like a hand in fixing this if anyone has any ideas.

Specs of things:
Primary Modem (router wirlesthingo): netgear CG3100
Secondary router/switch: Cisco Linksys E-2500
