Zandronum Public Server

[MartinGamingSVK]

Hello, I am new in this forum, I am finding the solution for my problem, but I didnt find anything to fix my problem. I want to create private server with my friends (I have Windows 7 Server with 24/7 using), everytime I get only error (2 errors exactly). GeoIP initialization failed. a "NAT discovery error: Fail to find an UPNP NAT." and I didnt move all time, and I dont know how to fix this, I do everything that I found and needed to do, like Port Forwading etc. but still doesnt work, can anyone help ? Thanks!
