hello,
stun allows data to get back into a network that is behind a NAT device
by connecting out to a server first, the only trouble is the server that
the stun client connects to cant be nat'ed, from what I understand anyway.
that hamachi is probably slow because all the data is proxying through a
3rd party network that is also being used by lots of other people that
are using hanachi.
I really cant see any way to directly connect to computers that are both
behind NAT devices that masquerade to each other and don't have any
forwarded ports / IP addresses without support from a 3rd device that
does have a way to accept connections from the internet.
I would try to find somebody that can spare you some bandwidth and run a
openvpn hub, you can use a little router running openwrt or look into
hiring a server, it depends on how much you want this tunnel.
