This can cause problems in a couple ways. It might not allow TCP connections (or UDP packets) from the outside (though most make exceptions for FTP). Second, it might be set up for NAT, static or masquerade. Even if you are set up for masquerade, there may be a "server" option that forwards certain connection attempts to the router to a particular computer. If you can't change settings on the router, try creating a server stack that runs someplace outside the firewall. Have all chat clients TCP to that. If you need only point to point, have b TCP to a. (It is sometimes easier to establish a dialog through a firewall with TCP than with UDP. This is especially the case with with mc port assignment limitations; the firewall might only allow a packet with exactly the source & destination swapped from one that recently went out.) Hope this helps. Dar Scott _______________________________________________ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard
