Testing for LoopBackIf you are reading this, it is probably because you already know loopback is not working and clicked the Help menu to get here. So you can skip down below and go right to "Installing the Loopback Adapter".
You can manually test for loopback by starting Opensimulator, then use a web browser to navigate to http://canyouseeme.org. Enter port 8002 and click Check Port. This must work. if not, fix the port forwarding issues and come back and try this test again. You may need to Open Ports in the firewall or disable it on the PC temporarily.
Your ports are known to be working now, so go get the Public IP of your system from http://canyouseeme.org. Use a web browser to navigate to http://(Public IP):8002. Use your Public IP where it says (Public IP).
You should get a log in page. If you get this page, loopback is working. If you do not get this page, loopback is not working in your router.
There are two ways to patch up a router that has no loopback. Both have one major issue, the viewer MUST run on the server. You cannot log into your server on the same LAN from a different PC is the router has no loopback and you use one of these two methods. If you must log in from a second PC on the same LAN, and also have hypergrid access you must replace your router. Also, if you do not need access to the hypergrid, you have no need for loopback, just use the Servers IP address for its DNS name, or leave the DNS name blank.
Method A) Add a Windows Loopback Driver
You will be able to teleport to your local grid when logged into another remote grid when you are using a viewer from the server.
