[Opensim-users] Hosting OPENSIM behind a firewall

[Ursula MATOVA]

Thanks a lot Tedd for your answer,

Well, at home I have 2 zones : LAN & DMZ ...
If I put my OpenSim Server into my DMZ, should it works ?

I'll try to setup your solution ... and then I'll come back to you  
with the result ...

Thanks again,

Regards,

Ursula.
