Hi Gwyn,
There are no stupid questions!! Everyone tends to miss something very obvious at times and usually screws things up..
Here is my setup..
I have these virtual hosts:
For my networking.. Internal IP are changed for example..
Internet IP: 184.70.53.242
Internal network:
Router IP: 10.10.10.2
Webserver: 10.10.10.4
Robust server: 10.10.10.8
Region server 1: 10.10.10.10
Nginx server: 10.10.10.18
port 80 is open on my router..
port 9000 is open on my router
My opensim .ini's point to either login.virtualrealmsgrid.com or hg.virtualrealmsgrid.com depending on the proper places.. I do not use Ip addresses..
My Nginx vhost.conf is setup like this..
server {
listen 80;
server_name virtualrealmsgrid.com www.virtualrealmsgrid.com;
access_log /var/log/nginx/vrg.log;

Now when I log in to opensim.. things look okay everything works.
Except when I logoff I get:
13:44:02 - [USER AGENT CONNECTOR]: Unable to contact remote server http://184.70.53.242/ for GetBoolResponse
and when I try to hypergrid I get:

I have looked every where for a reference pointing to the Internet IP 184.70.53.242 there is nothing..
I have no idea where OpenSim is getting my internet ip from.. Now I can work around that by yes as you thought, by pointing nginx to forward my internet Ip 184.70.53.242 to my robust server then both these errors go away.. But then I get
nginx passing its ip address to opensim when I hypergrid and the hypergrid fails because opensim sees my remote ip and the nginx ip and fails the hypergrid Ip verification.. And no matter what setting I have for remote ip forwarding in my nginx config..
I am more then a little confused.. Where have I messed up or what setting have I missed?
Any ideas??
Thanks
Todd

Hi Todd,
I know that this might not be very helpful, but as both a fan of Nginx and OpenSim, your thread interested me :)
I have what might be a very stupid question, so feel free to ignore me, but... as far as I can see, you are somehow redirecting the connection to 184.70.53.242:80 to your internal IP on port 8002. This is confusing to me, since http://184.70.53.242:80/ is actually being forwarded to your own webserver running Joomla. So a request to http://184.70.53.242/homeagent/a887910d-072c-42f2-92ae-17e69f65d118/ is being sent to Joomla and not to your OpenSim grid.
My question is how you manage to get both working at the same time *if you're using an IP address*. I supposed that if you had a virtual host, e.g. grid.virtualrealmsgrid.com, and configure everything at Nginx to point requests to grid.virtualrealmsgrid.com instead of using the IP address, this ought to work, because Nginx or any other webserver/proxy server/reverse proxy cache server is able to deal with virtual hosting. I fail to understand how you can accomplish that merely with an IP address (unless you explicitly list the port for it).
In my case, I have a grid behind a firewall, obviously with private addresses. There is a virtual host for the grid, which runs at the usual ports, but using that virtual host at port 80 will redirect users to a site running WordPress. The difference in my case is that, to keep things simple at the Nginx level, I explicitly add the port at the end, so I can be sure that :8002 is OpenSim, :80 is WordPress :) However, all the configurations in the OpenSim .ini files always use the virtual host, never the IP address, EXCEPT on the Regions file, where the INTERNAL IP address is listed explicitly.
Maybe this helps, or maybe I've completely misunderstood your configuration!
