That might not work. Explicetely enable natd divertion:
# Divert all packets through the tunnel interface
# This needs to be the very first rule
$fwcmd add 50 divert natd all from any to any via xl0
(xl0 should be your external interface - on the gateway machine of course)

It can be a number of things in the realms of TCP communications.
Things to try:
1) telnet to 'some site on port 80' => shows a working NAT
2) telnet to 'some hotmail smtp server' => shows port 25 is ok
3) call ISP if 2) fails.
4) if 2) succeeds, call ISP with specifics for that site
if 1) fails, slide over to:
