[Opensim-users] External Access to standalone

Sun Apr 21 19:36:37 UTC 2013

Thank you to everyone who helped all is now working - simple when it works!  I have a standalone diva distribution (0.75 opensim) with 5 regions working (ports 9000-9004)  and 3 simultaneous avatars working with insignificant lag, even with my ancient Pentium 4 Processors.  Curiously http://www.canyouseeme.org/  reports ports 9001-9004 as connection refused which proved to be a red herring. 

The primary issues related to the dynamic address not updating as expected and configuring the BT Home Hub 3 router (there is a lot of confusion on the web regarding versions A or B and firmware updates e.g. NAT loop back or not.) . 

-    A dynamic dns service linked a url to my address to my routers external address (dynamic)
-    The ExternalHostName was set to this external URL in both the MyWorld.ini and Region.ini files e.g. Region Config.ini
-    Port forwarding was set up for TCP and UDP on ports 9000-9004.

BT Home Hub 3 despite many BT community forum blogs comments must now be supporting NAT loop back (the router recognises that the external url refers to its own address). I am now able to access the server over the internal LAN as well. I need to add the BT Home Hub 3 to the open simulator site as working.

Next step is making is to make this robust/backups etc. Oh and recruit participants :)

Thanks again.

Based on my understanding and previous posts from Justin, Diva and others, this is my understanding of how it works:  When you start up the client and enter your name/password, it sends those details to the OpenSim login service. If your password is correct, it tells the region simulator that you're coming.  The login service then sends back to your client the IP address and port to use to enter that region based on the information in the regions.ini configuration file.  Your client then connects to the region using those details.

This can be any number of issues related to your networking setup.

The  External login gets as far as [SCENE]: Region Central authenticated and authorized incoming root agent XXXXX (circuit code 230241706) (using the rest console).  Firestorm then fails giving the message "Waiting for region handshake" after a number of attempts.
