OpenSim Adventures, Part III

World building is harder than it looks!  The Resident Geek and I have spent some hours now, bouncing between settings menus, user manuals, forum posts, and trying and re-trying to get a region connected to OSGrid.  It runs OK, and we can see it on the map, but it's not accessible.

It seems to be some sort of port forwarding the FIOS router, the LAN router, the software firewall, or the OpenSim .ini  settings.  Or possibly something called a "loopback" issue.  Whatever it is, we have not yet hit the magic combination of buttons to fix it.  When the Geek started opening Advanced settings windows with the warning, "changing stuff here could cause your computer to stop working and render Iowa uninhabitable," I called a halt.

I must make a bit of a correction to some earlier posts about OSGrid...I've been saying they have between 6,000 and 7,000 regions.  Yesterday, they had about 9,500!  Wow, such explosive growth, I thought.  But the OSGrid website explained that because the regions of the grid are user-hosted, they come and go with great abandon.  The "regions on the grid" number is a lot more like Second Life's "residents online now" changes a LOT.  In fact, it changes so fast that OSGrid says even the published number can be off by 50%.  Certainly my poor little region of St Alda was on again, off again all day yesterday!  Talk about a world in flux.

Whew.  What we need here is a geeky high school student.


  1. *packs her bag and waits at the Caledon Train station for the non-stop to your region* And with great enthusiasm! I am so happy for you, for even attempting something like this! Congratulations for getting even this far!

  2. good luck! i'm having port forwarding and loopback issues and also have FiOS! my sim is up on the OSGrid and you can see it on the map - i even loaded my home OAR onto it - but my TCP does not match my OPP or something! what a pain! -)

  3. Ener, our setup has two routers...the Actiontec one for FIOS -- that's what actually connects to the internet. And a Trendnet wireless router that runs the home LAN and connects everything together. We had to go into the setup for BOTH routers, and make sure that a range of ports was forwarded (we used 9000-9010. 9000 is the minimum; more will give you a range to allow creating more than one region). Set the forwarding to include both TCP and UDP. Make sure you identify the network DNS address of the computer that is running your simulator. This is in Network and Sharing, view full network map, hover mouse over your computer's icon in the map.

    I set the OpenSim "listener" port to 9000 in the OpenSim.ini file, and the region port to 9001 in the region.ini file, but this may not be necessary, different authors have different opinions.

    I don't know if it made a difference, but I also installed a "microsoft loopback adapter" from the list of generic Windows network adapters. I did not bridge it or connect it in any way, just installed it. It shows up in Network and Sharing as "unidentified network, limited connectivity"
