ICC Help: firewall

Connecting to ICC through firewalls or proxies

Do you connect through your local area network? A local network usually connects to the Internet through a firewall (a security measure to control what is received or sent to the Internet). BlitzIn for Windows can not connect through some firewalls. Winboard and Icarus can connect through many firewalls, if you use the right settings. Explore the menu on those interfaces. On Winboard, the firewall settings are under Help / Index / Firewalls.

http://www.chessclub.com/helpcenter/interface/trouble.html has some more information.

We cannot help you configure your firewall or provide any other such technical help, and do not provide technical support for third-party interfaces. The documentation that comes with each interface is the best place to look.
