I know how to portforward and I did it on at least 5 different routers at different places. But at home, it does NOT work. I can't figure out why.
I tried different routers, even routers that I managed to portforward in other places, nothing works. I did many many tests and I can say for shure that the problem is not the portforwarding configuration, it is not the router, and it is not my computer or any firewall on it.
What could be the problem ? What can I try? My ip-adress.com is not the same as my WAN IP (that I can find in my router page), does it mean something ? I'm looking for the complete lists of things that makes my portforwarding not succeed.
Here is my connection collaboration :
MyPC --> WIFI ROUTER : TP-LINK TL-WR841N --> MODEM : Motorola SBV5121 --> Amplifier 2 Data : GVR-2440C --> OUTSIDE HOME CABLES.
