'If it is not possible to shut-down your firewall, you will need to configure your router or firewall to allow port 1000 (UDP & TCP) for the best possible connection. Some other ports you may need to open are as follows:
44301 [UDP & TCP] - PunkBuster Service
45301 [UDP & TCP] - PunkBuster Service
49928 [UDP & TCP] - Uplay Service'
How you enable that - depends on the type and make of your router - so you should either contact the maker or your ISP for details.
