I was following these directions...

OS X FIREWALL:

To open the OS X Firewall for Gnutella access, please do the following:

1. Open up 'System Preferences'
2. In 'Internet & Network', open 'Sharing'.
3. Select the 'Firewall' tab (your Firewall should be on)
4. Select 'New...'
5. From the 'Port Name' drop down box, select 'Gnutella/LimeWire'
6. Select 'OK'
7. Restart your LimeWire application.

OTHER FIREWALLS:
Please allow both TCP and UDP connections for optimal performance

but only problem is when I do the port name drop down box, there is no 'Gnutella/Limewire' port to select. What do I do?


P.S. I've also attempted to input the UDP and TCP port number on my own. I've used 64049 (for both, once) and 6346 (for both, another time).

See OSX Firewall settings for Tiger because even if you're using an earlier OSX the instructions are almost identical. Yes change port to another if you'd prefer.

Firewall that LW may detect might not be your softw firewall but your modem/router's internal NAT firewall. Check Connection problems? Check here first! (click on link)

BTW many OSX users don't even use their OSX firewall. Disabling it at least temporarily will allow you to know whether any firewall detected is from OSX or elsewhere.
