NAT

First things first- I had this problem since I went mutiplayer on CO.

Most of the games on ef and normal CO I cant join.
At the ping side it has a big red X, and when I try to join it, it says:

            NAT negotiation failure occurred, unable to connect (guy I can cannot to)

I held it in for mouths but when I tried joining a friend on EF and couldn't, I just got mad.

Dose anyone Else have this problam? Is it fixable? If so, how do you fix it?

Its preventing my from playing with my EF buddies :'(

A very common problem for many people, sometimes it fixes itself depending on the day, its to do with your connection.

I suggest trying to forward your COH ports, might help

How do you do that?

I had the exact same problem with MW2..
I fixed it by going to the specific site for your router. and then chaning some numbers at the ports.
I looked up on youtube how to do it.
just type in your router name + NAT problem and search..

That really dosent help.

I forwarded my ports, more games are working, but still alot dosent.

Its fine, anyway

Maybe it sounds a bit weird but I had the same problem and I found out that I only get the problem when another computer is online as well in our network.

So for me if I'm alone i can play CoH, if not i can't. Check out at home.

NAT :- Network Address Translator

Its a sort of router for many networks

the problem is that ur friends NAT router doesn't allow connections on the ports ur using , so forward ur ports

It can be done by entering the Ip adress of ur router in the address bar

like ]http://[IP address redacted] etc

ull be asked to enter a username and password

most prob it will be admin,admin or admin,password

go to network settings- advanced - NAT settings...


Cheers :) :) 

Yeah thank you, but Im not allowed to do that ;)

Thats sorta what I done, but thanks anyway ;)

No problem guys , BTW what do you mean "you are not allowed to do that"?

I have parents ^^ and I dont need to do it.

I see
