[Opensim-users] Help: Opensim behind an ISA Firewall

[Teravus Ovares]

I would suggest setting the internal IP to 0.0.0.0 or the main IP
address of the respective network interface to listen on and suggest
setting the external hostname to a hostname that refers to the IP
address that you expect people to connect on.  (0.0.0.0 means listen
on all interfaces, but it doesn't always work with multi-interface
systems)

You are also going to need a routing rule to forward requests from
within your private IP space to the public if your router doesn't
support NAT loopback directly.

Regards

Teravus
