Secured My Wireless Network - Leopard Made Me Do It
I finally secured my wireless network (sorry Sean, whoever you are.  Plenty of WiFi around here anyway).
Leopards new security system would net let me enable file sharing (port 548) on my IMac without opening that port on the firewall. I didn’t want the port opened - because I wanted to tunnel port 548 to my laptop with SSH over the public (internet or wireless) network. It was too big a risk to run file sharing with port 548 open to the public, so I secured the WIFI network. Hope I can get my AppleTv to connect!
