Issues logging on to bnet...

[[vL]Kp]

For inbound, Diablo only needs UDP port 6112. The others are frequently used when multiple users are sharing a single public IP address, and each port is mapped to one of the users. Even without allowing inbound UDP, it should be possible to get on battle.net, but you would not be able to play games (only chat). For outbound, Diablo needs to send to UDP port 6112 on the battle.net server and to connect to TCP port 6112 on the battle.net server.

Could we get a more detailed description of the failure mode? Is there anything in BnetLog.txt?
