Hi Beaver!
GR is okay on my PC - I have been playing on UBi almost 2 years!( I have version 1.4 patch installed)
Even with my firewall turned off, I still cannot connect to your server. (Although Ghost recon is listed as an exception, even when it is on!)As far as routers go, I have no clue. If it helps I am using a Speedtouch Broadband modem and it is connected through Wanadoo.
Anybody else heave a similar problem, or better still, know of a fix? (Or am I the only poor sad barstard on the web...?)
