This is a fairly common problem and im one of those individuals that have tried everything on froums to opening ports to configurating my router and for some reason i still get the NAT Error when trying to locate an incoming listening connection. For some reason what ever i try its always on a yellow smiley, and i think it may be running at a good speed which is from 5kB/s rising up to 20kB/s. But whatever i try i always get this NAT Error i want to be able to experience the green smiley lol, but anyway i remember like a year ago using Azureus and the listening port was fine so i reckon it may be something to do with the router settigns, from then i had a period of trying to configure my router for xbox live which then turned out to be a really simple problem. A matter of opening up the wireless game adapter and slotting this card back into place. Anyway i think the problem i have is not exactly complicated to fix, but it may be since all the other resolutions worked with other people but not with me. Please try to help me, i have experienced many problem with my networking, i would appreciate any input. (please give step by step informationa s im not a computer genius more like an intermediate.) Thanks Again, British_Command.
