Do any of you guys know of any other program that can share files just like hamachi does? I heard of other similar programs : Gameranger, Wippien but I don't think they support file sharing.

Anyway I'm asking this because a friend with which I want to play some games can't use hamachi, I donno why. Also speaking of which, why do some people have problems connecting to hamachi and are there ways to get around it? For those of you that use it, it's when it displays that yellow star.
 

He has to forward the ports Hamachi uses in his router and add an exception in Windows Firewall if it is enabled. Also raise the Hamachi network adapter priority to the top of the list under advanced network settings.

If you want to share specific files then he has to enable file sharing over Hamachi and you both have to set to share the content/directories in Windows that you want each other to be able to access.
 

The hamachi community would be your best bet with this one. http://www.hamachi.cc / http://community.logmein.com/logmein/

I've been using it for a few months now for tunneling while out-and-about. love it.
