Why is it that when I click Browse Host Limewire tries to browse a host with an ip of 192.168.*.***:****, which, of course doesn't work!

I have that as an internal ip, can limewire detect my external one that would actually work as a browse host?

My internal ip is: 192.168.1.100:6346, but my external one is 6*.10*.5*.*:6346, does limewire know this? Can people browse my files? Every client I have tried COULD detect your true external ip address, does limewire? Am I one of these 192.168.*.***:**** people that cannot be browsed? Cannot be chatted with?

How do I set my external ip in Limewire so I can avoid this whole mess?

Thanks in advance!
