[Opensim-users] Opensim-users Digest, Vol 19, Issue 7

[Thomas Ringate]

Keep in mind this is only going to work for that one PC you add the windows loopback adapter to.  For instance, if you happen to have a another computer on your network that you try to connect to the server you are running on your primary computer, it will have the same problem you are having now.  You have the loopback function taking place at the point you connect to your local network so other computers on your local network know nothing at all about it and depend on the router to do loopback, which it can’t.  However this other computer will work just fine out  on the global opensim worlds because it does not need loopback to work  with servers that are not on your local network.

Thanks so much Fred, your explanation was exactly what I needed to configure the Windows Loopback Adapter. I will remove the line in the Hosts file and configure the Adapter and see if that helps me. 


A question. Do I need to do anything to the Etherneth connection? I mean right now I had configured it so that this PC got a static internal IP 192.168.2.10. Do I leave it alone and do nothing to it and just configure the windows loopback adapter?

  I would not use the Hosts file 'trick' on a server that also has the viewer.  The fact that you need to edit hosts file indicates that the router cannot loopback.    I use the Microsoft Loopback Adapter.

  What happens is that the server broadcasts your public DNS name to clients not as a name, but as an address.    The server first does a DNS lookup and via hosts, finds the 127.0.0.1 loopback.   It will broadcast this 127.0.0.1 address  to a remote WAN client, and they cannot connect.    Yet it works for you.    But without loopback, you cannot connect.

  On Windows, you can add a software loopback adapter for the Public Port to loopback the public IP to the server, which allows the server to send the public IP to clients.

  Installation instructions: https://technet.microsoft.com/en-us/library/cc708322(v=ws.10).aspx

  Once it is installed you have  to set it up.  It will be in the Control Panel->Network Connections, as "NAT Loopback".  Its just like an Ethernet driver.   Open it, and find Internet Protocol Version 4 (TCP/IPv4) and change its properties.  I click "Use the following IP address" and enter my PUBLIC IP in the IP Address box.   No Gateway is needed.  Under DNS, I used my routers IP address so it can do the DNS lookups.    Or you can use Googles super DNS of 8.8.8.8. and 8.8.4.4

  Once enabled, this will make any reference to the Public IP address route right back to the system itself,  just as the router should do.    And WAN users get the correct Public IP sent to them, instead of 127.0.0.1

    Thank you Garmin. I have configured my internet connection to be a static
    internal IP which is 192.168.2.10. Following your suggestion I replaced the
    0.0.0.0 with that IP.
    Result is: The console shows:
    17:48:30 - [SCENE]: Region Arcana Welcome authenticated and authorized
    incoming
    root agent Isis Ophelia 1b77be9b-248e-400b-a4ca-499d0aa06d77 (circuit code
    40308
    2697)

    And the viewer tells me: We are having problems connecting. There might be
    a problem with your internet connection or the Arcana World Grid.
    So pity this does not help :(
    Thank so much though :)
