Okay - let me rephrase the question.
Do you get the same error message from the server if you access it from some
machine which does not go through the firewall (and is not the firewall
itself)? Even if you have to temporarily set up a client to test this, I
think it would be useful, because it would be good to know if the server
generates this error independently of anything the firewall is doing to the
packets.
Also, have you tried adjusting the MASQUERADE rule as I suggested, so it
applies to the external interface only, as this may have a bearing on the
problem?

Antony.
