Opening Port 6112 with ICS

[Chico_Marx]

Get a BattleNet message that I need to open port 6112 to recieve UDP packets on a client machine accessing the net through ICS on another (server) machine connected to a cable modem. No router, no firewall. How do I open the port? On the client or server?

you have broadband and no firewall?

not good indeed

Temporarily. We're still trying to figure out why the IP lease doesn't get renewed and an active firewall just complicates the research. Looking to do a firewall with either software (ZoneAlarm) or hardware (Linksys router). Meanwhile, how do I open 6112?
