That's what I was hoping to do, but can it be done directly from my app? As I understand it, ip6fw is the firewall for OSX. Assuming 192.0.0.3 is the remote IP address and 9878 is the port I'm using, is this the correct syntax for this?

           ip6fw add deny tcp from 192.0.0.3 9878

Thank you,
