Is it possible to make a lugormod server if I have modem instead of router? I mean I am unable to find the way to open ports (w/e... to make the server work).
OK well I added "jampDed.exe" to the exceptions in firewall. I also opened 29070 port there. And I did the same to my antivirus. But it is unable to connect to the server (I mean I use two different computers and two different internets).
Once I even turned the whole firewall off (the same to antivirus) but no one saw this server...
And I also use win7

Hello, did you try to access your router settings?
To do that, follow these steps.

1) Go to http://www.whatismyip.com
2) Copy your IP address and paste it in browser address bar
3) If it asks for your username and pass try admin for both (username and password)
4) When you've accessed the router go and try to find port forwarding tab. If you can't find it take a photo and upload it here please.

Best of luck!

Thanks, but ... I do not have router there.
And I also mean I tried that multiple times

Do you know how to use CMD? (Command prompt), if so start that and enter ipconfig, find "Default Gateway" line and copy that IP address. Again paste it into your browser address bar and try to access your modem. Reply if it worked or not.

Sadly, it didn't work.

Would modifing these settings work/help?
This is the main screen when I connect modem to computer.

No answer....?

OMG
