[Opensim-users] strange handshake problem

[Fleep Tuque]

I had similar symptoms on my home network and in my case it turned out to be
avast (anti-virus/spyware) that was blocking the UDP traffic, not my
firewall.  Worth checking perhaps if you're sure the right ports are open..

Keep us posted and good luck!
