[Opensim-users] Trouble with Architecting a Scalable ROBUST Solution

Tue Oct 9 12:49:09 UTC 2012

Hi Chuck,

I'm confused, are you trying to only allow access to your simulators from
inside your network?  Can you help us better understand what your goals are
with this set up?

The networking piece is the most complicated part of setting up Opensim,
IMO.  This thread follows my travails getting our campus grid networking
set up where it appears I was trying to do the exact opposite of your goal
- allow users from outside my network to connect to the simulators on a
network with 1to1 NATing.  It may have useful information for helping you
troubleshoot your situation:

Another terrific resource when trying to troubleshoot connection/login
issues is Justin's blog post explaining the login process in great detail,
which is located at:

http://justincc.org/blog/2011/05/26/opensimulators-login-process-and-common-login-problems/

In my experience, I've never gotten any grid or simulator configuration to
work using a 10.x.x.x address, since the internal IP can never be resolved
outside the network.  But maybe I'm not understanding what you're trying to
do with this setup.

Sincerely,

- Chris/Fleep
