Currently, if I have 10.6 server firewall turned on, I can’t netinstall at all. It just hangs. If I turn off the firewall, everything is fine. Any pointers for this issue?

After holding down “n” on the client machine, the globe comes up and then the computer just sits there with the swirling spinner thing.
