<DIV>opensim requires the loopback function to work for it to operate
correctly.</DIV>
<DIV> </DIV>
<DIV>Loopback can be implemented in a few ways as has already been
suggested.</DIV>
<DIV> </DIV>
<DIV>If your server and viewer are on the same computer, using the windows
loopback adapter will solve the problem for you.</DIV>
<DIV> </DIV>
<DIV>If you are running several servers on an internal network, or you are
trying to connect to a server on an internal network from a client, ”your
viewer” which is on a different machine on the same internal network then the
router must support loopback.</DIV>
<DIV> </DIV>
<DIV>Most new home routers do not support loopback, and even those that claim to
support it usually do not correctly support it. This can be seen using a
sniffer you can see that addresses in the individual packets often get the
address of the router, rather than the actual address of the sending
computer. Fortunately this problem usually results in a timeout and
opensim usually will do a retry and these “broken servers” for whatever reason
often get it right more than they get it wrong.</DIV>
<DIV> </DIV>
<DIV>If you do not have a router that correctly supports loopback, and you are
not running everything on the same computer your only hope is to use a VPN to
get outside of your local network so the remote router can do the loopback
functions for you.</DIV>
<DIV> </DIV>
<DIV>In my case I have Verizon FioS which uses the Actiontec modem which does
not support loopback according to the manufacturer and using a sniffer I can say
they are correct. It does not. However Verizon has implemented
something in their head end some how that “tries” to implement it. It
works right about 40% of the time.</DIV>
<DIV> </DIV>
<DIV>I found after hours and hours of discussion with Verizon technical support
that their commercial costumers solve this problem by simply placing a router
that does support loopback directly on their ONT and then connecting the
Actiontec router to that router. That is exactly what I have done using an
old Linksys router and everything is now working fine.</DIV>
<DIV> </DIV>
<DIV>The correct term of the feature we are talking about is “NAT
loopback”. <SPAN class=_Tgc
style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT face=Arial><FONT
color=#222222><B>NAT loopback</B>, also known as <B>NAT</B> hairpinning or
<B>NAT</B> reflection, is a feature in many consumer routers which permits the
access of a service via the public IP address from inside the local
network.</FONT></FONT></SPAN></DIV>

<DIV><SPAN class=_Tgc style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT
color=#222222 face=Arial>I believe your issue is the perfect example of why
opensim requires loopback to work. The address of your local world is
known by it’s NAT address, outside of your local network which is an un-routable
address.</FONT></SPAN></DIV>
<DIV><SPAN class=_Tgc style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT

<DIV><SPAN class=_Tgc style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT
color=#222222 face=Arial>By messing with your host file you can fake things for
yourself inside your local network, but the IP address opensim is sending is
either your external IP address or the local IP address. It can not
determine when to send one or the other so it sends what you tell it by a
specific IP address or the domain name.</FONT></SPAN></DIV>
<DIV><SPAN class=_Tgc style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT
color=#222222 face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN class=_Tgc style="LIST-STYLE-TYPE: decimal; LINE-HEIGHT: 1.2"><FONT
color=#222222 face=Arial>With a router that supports NAT loopback, you use the
domain name and both internal and external users work just fine. If the
router does not support it, and you are only running one opensim server on your
local network, if you use your NAT address, only local users will work
fine. If you use you external IP address only external users will work
fine. If you run multiple opensim servers your router must support
loopback if you expect remote users to be able to move between your regions on
the different local servers without problems.</FONT></SPAN></DIV>

<DIV dir=ltr>Hi Isis, please see comments to your original post:
<DIV> </DIV>
<DIV>Of the top of my head, you need to forward the simulator ports on
the router and Windows Firewall (I completely disable Windows Firewall
on all my computers).</DIV>
<DIV> </DIV>
<DIV>Adding your domain name as a loopback alias in the hosts file is a
sign that your router is unable to handle loopback calls, i.e. is unable
to resolve your domain name to your external IPand allow traffic to
travel back into and through itself. There are other software solutions
to this, such as using a vpn while you are logged into the viewer.
Fiddling with the hosts file is not recommended.</DIV>
<DIV> </DIV>
<DIV>I haven't seen your regionsconfig.ini, but make sure that the
address entry contains your domain name andnot your ip address (internal
or external)</DIV>
<DIV> </DIV>
<DIV>These are the things I can think of off the top of my head, I hope
it helps :)</DIV>
