<div><font size="2" face="Arial">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. </font><font size="2" face="Arial">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:</font></div>
<div><b>If your local systems send packets to the -public- (external)
IP<br>and port of your internal servers, then if the filtering is turned<br>on
then the device will deny those packets; when the filtering is<br>turned off,
the device will re-address those packets and send them<br>back inwards. In this
situation, the source of the connection is local<br>and the destination ends up
being the local server, but the address<br>used by the local computer was the
outside address instead of the<br>inside address.</b></div>

<div><font size="2" face="Arial">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

<div><font size="2" face="Arial">Nicky,</font></div>
<div><font size="2" face="Arial">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.</font></div>
