[Opensim-users] NAT & Corporate Firewall

Wed Mar 30 15:49:30 UTC 2011

Yep no luck with that one either.

[University of Cincinnati]
RegionUUID = 5985af1b-4223-4a12-ba87-1c3830a44e97
Location = 9000,9000
InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = ucsim1.irc.uc.edu

This is what I see on the opensim.log:

On the client side it gets to Region Handshake and then hangs..  Users from
on campus are still able to log in though.
