Hopefully there is a way to do this. But basically, I would like to use Panther's built-in firewall. It works perfectly, except I would like the other computers on my home network to be able to always go through the firewall, and have firewall rules only apply to machines outside the subnet. The reason for this is because there is only one network adapter and the outside world sees it through a cable modem, and I am also using it to share the cable connection with the other machines on my home network. Hopefully that made some twisted kinda sense. Thanks!
Just to reiterate, I want to set up my firewall so that SSH is open to everyone, but CUPS is only open to the other machines on my network, and Internet Connection Sharing is open to the other machines on my network :-/
