I have problem with port forwarding on my Siemens C-010-i ADSL modem while it is working in router mode. This modem works by default in bridge mode, and it worked that way when I first got it. Everything worked fine then, I could normally host games online and everyone could connect to me via internet normally. That was when modem was working in bridge mode. Then I had to adjust it to work in router mode (because of my home network and other wireless network aswell). It works in router mode just fine, I can use internet normally and my home network works well too.
But for example I can't start any online dedicated server on my computer so other players can connect to it and play games online. I can start dedicated server for my home lan normally, everything works well inside of my private network, but this Siemens modem/router is blocking computers to connect to me via internet.
Ok it is normal behavior, but I just can't set it to forward specific ports so anyone can connect to me. In my modems settings there is option called "Virtual server" which is used for port forwarding but when I try to adjust it, it appears to work fine, but still no one can connect to me via internet.
If a game(dedicated server) is using port 2302 for communication over internet I set up my Virtual server this way:
Start port: 2302
End port: 2302
Private port: 2302
Port type: TCP
Host ip address: XX.XX.X.XXX <- here I enter my computers (which is hosting game) ip address
I save this settings to modems flash and reboot it. The options are saved to modem, but still my server isn't visible over internet.
I have tried numerous combinations of settings with it and enable DMZ on my modem, but nothing worked. I googled and googled, and asked on forums about this problem, but no one was able to help me.
I would like to ask those who have/had this modem or have experience with it or know something about my problem, to help me, because I'm desperate.
