Try the missing combination
InternalAddress=0.0.0.0 ExternalHostName=ucsim1.irc.uc.edu

Hi Edmund,
Nod I've tried that permutation too, no luck. Here are the
combinations I've tried so far:
Test 1: InternalAddress = 10.23.23.x ExternalHostName = 129.137.2.x
Result On-Campus: FAIL Result Off-Campus: FAIL
Test 2: InternalAddress = 0.0.0.0 ExternalHostName = 129.137.2.x
Result On-Campus: FAIL Result Off-Campus: FAIL
Test 3: InternalAddress = 10.23.23.x ExternalHostName =
ucsim1.irc.uc.edu <http://ucsim1.irc.uc.edu>
Result On-Campus: SUCCESS Result Off-Campus: FAIL
Test 4: InternalAddress = ucsim1.irc.uc.edu <http://ucsim1.irc.uc.edu>
ExternalHostName = ucsim1.irc.uc.edu <http://ucsim1.irc.uc.edu>
Result: Opensim.exe crashes
Leaving at the default InternalAddress = 0.0.0.0 and ExternalHostName
= SYSTEMIP works for on campus users but not for off campus users.
Has anyone else run into this problem with a campus or corporate
firewall? How did you resolve it?
Thanks again,
- Chris

Hi Fleep.
Maybe you've already tried this, but I'd suggest setting
ExternalHostName as your external IP (129.137.2.x) rather than your
hostname (ucsim1.irc.uc.edu <http://ucsim1.irc.uc.edu>).
Behind NAT, some places (including Amazon EC2, I found) use an (IMHO
evil) thing called Split DNS (or "Split Brain DNS"), where the IP
address you get inside the firewall is different to the one you get
outside your firewall. This may be causing your OpenSim box to think
that ucsim1.irc.uc.edu <http://ucsim1.irc.uc.edu> is 10.23.23.x
rather than 129.137.2.x.
HTH, let us know how you get on.
