[Opensim-users] Region handshake does not complete

[Nicky Perian]

Gary,

It appears that all settings on the security tab depend on the firewalls being enabled.
Steps taken.
Enabled firewalls.
Cleared the check at Filter Internet NAT Redirection for IPv4 Internet Only 
Cleared the checks for port trigger forwarding.
Tested.
It worked.

Thank You!!
Nicky

>Nick,
>You need to un-check the 'Filter Internet NAT 
Redirection.'  When checked it will prevent the redirection you need.  
The hosts file setting seem helpful in getting the TCP mode login process 
started when NAT loop back is not working.  This really isn't helpful 
because it when UDP kicks in the NAT loop back is still needed. Here is a link to a cisco discussion of the issue: http://homecommunity.cisco.com/t5/Wired-Routers/What-s-the-purpose-of-Filter-Internet-NAT-Redirection/td-p/63857  
which contains this:
>If your local systems send packets to the -public- (external) 
IP
>and port of your internal servers, then if the filtering is turned
>on 
then the device will deny those packets; when the filtering is
>turned off, 
the device will re-address those packets and send them
>back inwards. In this 
situation, the source of the connection is local
>and the destination ends up 
being the local server, but the address
>used by the local computer was the 
outside address instead of the
>inside address.

>>>The CISCO 'NAT loop back' item is 'Filter  Internet NAT Redirection.'   I'm not at my usual location so  I can't check how it's set on my e3200.  I  think un-checking that option (the default) allows the  redirection of your external IP back to your local LAN.  It's  one of the firewall settings.

>>>>>Nicky,
>>>>>At handshake time the opensim server sends  the viewer the resolved IP address of the region being connected  to.  I'm assuming that would be your dyndns domain name + a port  number.  However the server send the resolved address, not the  domain name.  So the viewer will be getting the external IP + port  number.  This can work if you local network router has NAT loopback  enabled.  If not the viewer attempts to use the address and doesn't  reach the server.  The host file settings would be effective if at  handshake time the server sent domain names to be resolved but it  doesn't.
