You need to make sure that you have defined your external interface in the
file external.if. I do not remember where it is under NT but most likely
%fwdir%\conf\external.if.

As for SR: Based on what you have shown us, SR is working and you should
just use it. SR may simply be hiding the traffic from you to keep you on
your toes :)

Seriously though, if SR is not working even without IP NAT Pools defined,
but the traffic reaches the server, then most likely routing or an MTU
problem is at fault.

You may want to have someone on the list try to connect and see if they
can help you diagnose the problem. I had a problem with SR, NAT, and a
firewall on the same network as the SR gateway all conspired to cause me
grief.
