allow AIM through firewall
I just got my Red Hat 9 system working as a DSL gateway for my home network. Now I would like to activate a firewall as well. The pretty little Red Hat firewall config tool has just three options...no firewall, medium, and high. If I set it to medium, everything seems to work ok, but I have a few programs that I would like to also permit access to the outside world, most notably AIM and Quake3 (running as an app on the windoze boxen and as a server on the gateway). Any suggestions how I might go about adding permission for these ports to the configuration that "Security Level Configuration" produces by default?
