Troubleshooting manually

You can just run Help-Network Diagnostics and see what it ays. Or troubleshoot it manually. The diagnostics do what is described below , but sometimes you just need to know more. So this is a list of things to try.

What is needed:

It needs two things: Open ports, and loopback.

First take a look at this on Port Forwarding.

It has a list of routers and instructions and links to which can help once you identify your router type.

Which ports? You need to open 8001, 8002, and 8004-8010 to have room for expansion. Don't do 8003 for security reasons. These can be done in ranges, like 8001-8002 and 8004-8010. The latter ones are for regions - you need one port per region, so this would let you have 7 regions. Add more if you want - nothing wrong with opening up to 8020 or 8030 or so. And they need to be both TCP and UDP. Your router will have a button or a pulldown to select UDP, TCP, or both.

How do I know this worked? You can tell if it worked by starting Opensim, and then use a web browser to go to, and enter 8002. If that works, the ports are fine.

Mine looks like this: screen

Loopback Tests:

The second part that has to work is loopback - either your router supports it, or not. You can immediately tell if your loopback works after running the above CanYouSeeme tests. You use your web browser to navigate to http://(YOUR PUBLIC IP):8002/wifi . Mine was Of course, your IP address will be different than shown above, so use whatever it shows you. If the system is working, you get a web page, if not, it will just hang.

If it works, go the the Settings->Advanced Settings menu, and click the DNS Name field:

Advanced Menu

Click it and you get a pop up:


Either click Next Name until you see one you like, and press Save, or type a name like '". The name will not work with spaces, and no funny characters. Then click Save, and restart Opensim.

Now use that same name to add the Grid Settings to your viewer, ( ot kust use Onlook, it knows already) and you should be set to go.

What to do if the loopback test fails.

Click this link and add the built-in windows driver. Then start over at "Loopback tests".
