Addressing nat issues

[Giacomo Di Ciocco]

Hello everyone,
when connecting to an host behind NATs (Networks Address Translators), 
theres to do port forwarding from/to every NAT in the route; i know it 
is possible to address this problem with the "Listening VNC viewer" 
feature which makes the viewer to bind a port and get called by a remote 
server which is the behind-nat-host; but whats the solution if both ends 
are behind some NATs ?

A solution i can see is to run a special, listening, "VNC Proxy" 
application in a host with public IP address and let the 
behind-nat-hosts connect to it; it will do the trick, forwarding the 
data through the incoming connections.

Theres anything like this around ? Theres anything for Linux OS ?

Regards,
Giacomo.
