I got an iPod Touch today and I'm while I was testing out some apps I noticed that I cannot connect to my MacBook Pro. If I try to ping it I get no response. Going to the Mac's address in a browser (web sharing is on) I don't get any response either. I cannot connect to for file sharing either. I have turned off the firewall in OS X and rebooted the computer with no change. All sharing options are enabled. If I run "sudo ipfw list" I get this: "65535 allow ip from any to any". It appears however that Snow Leopard allows connection from outside the local network, as Internet, BitTorrent, Mail etc. works as usual. I've tried turning the firewall off in the router but connections are still blocked. Any ideas?
