Thanks very much.
You have elucidated the issue for me.

Yes. What I call my server, "helen", is attached to an ADSL modem on eth0.
It is also attached to a Linksys WRT54GL router on eth1.
which is the link to my home network.
I have an external IP address 86.43.71.228 .

I did look briefly at the shorewall documentation on Port Forwarding,
at <http://www.shorewall.net/two-interface.htm#DNAT>,
but I thought it was only concerned with inward port forwarding,
while I wanted outward port forwarding.
But I see on reading it more carefully that I was mistaken.
