[Opensim-users] strange handshake problem

[Justin Clark-Casey]

Very strange.  The handshake message indicates that the login has returned a region IP and port to the viewer and that 
the viewer is now trying to establish a UDP connection with this region.

But if your ports are open I'm at a loss as to why you're not seeing some indication of the connection attempt on the 
relevant region console.
