You need to tell asterisk that you are operating behing NAT. You can
do this with the following entries in sip.conf:

[general]
port=5060                       ; Port to bind to
localnet=192.168.0.0
localmask=255.255.255.0
externip=81.82.83.84
outside_addr=81.82.83.84
bindaddr=192.168.0.200
nat=yes

Where bindaddr is the private adddress (natted address) of the
asterisk box and externip/outside_addr are the address your router
presents to the outside world. (I think one of these entries is
redundant, but I know which off hand).

To accept incoming calls from FWD you will need to port forward UDP
traffic on port 5060 to your asterisk box, but this won't affect your
ability to make outgoing calls.
