I recently moved to another city and am now having a problem with my router. After hooking everything up to the new modem, it seems that even though my ports are forwarded in my router's settings, they aren't actually forwarded. I am using the same router and computer I have been using so I figured it had to be the modem, but when I hook the computer straight up to the modem, the ports are open. I have tried 2 different routers and neither of them work. I have also tried a DMZ as well as forwarding and that doesn't work either. I have also tried disabling SPI Firewall Protection and that didn't help. I am reasonably intelligent when it comes to networking so I know how to port forward, but this has me stumped.
For the record, I do have my IP static. I am pretty certain that the router settings are correct being that when I forwarded the ports originally at my old house everything worked fine. Before I tried the second router, I used the reset button on the back of the first and that didn't help. I've also updated the firmware on the second router which also didn't help.
So basically I moved, and with everything being the same except the connection, my ports are closed. Switching routers and forwarding didn't work. DMZ on both routers didn't work. My IP is static, the ports just aren't open. When hooked up straight to the modem, the ports are open. Does anyone have any idea what the problem is?
