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

[clive gould]

Hi

I've just installed OpenSim 0.66 on a CentOS 5.3 linux box on a class
A subnet behind and insitutional ISA firewall.

Opensim is running fine in standalone mode but I cannot connect to it
remotely using a Hippo client running under Windows Vista.

The server has a valid class C address on the Internet side of the ISA
firewall/NATbox of 195.194.82.16

The hippo client successfully connects to the server via TCP and will
authenticate a user.

However connection fails when the client user login gets to the region
handshake, which I presume uses UDP.

The problem comes down to the fact that Opensim is listening for UDP
connections on port 9000 on the servers internal IP of 10.100.0.22

I've looked that the packets on the client machine and it appears that
they're not getting delivered to the server as the client is using a
destination IP of 10.100.0.22 for the UDP connection, which of course
is not routable over the Internet.

Is there any way of getting the client to send the UDP packets to
195.194.82.16 instead of 10.100.0.22?

Thanks in advance
