Need help Please!

If any of you have ever played Far Cry online can any one please enlighten me to why
every time I go to create a server and then get my mates to connect to it this see it as 9999 Ping and it is greyed out?

Thought it was just my comp but got mate to create server and he gets same to....

I have tried opening ports ports:

TCP: 40000 - 42999
UDP: 41005

Far Cry game ports:


Outgoing port 49001/49002
Ingoing is client dependant

But still no joy...?

Can play in any one else's server fine?

What are we doing wrong as me and mates are new to plying Far Cry online.
And this is the only game we have problems online with.

Thanks for your time ... : )
