Thanks a lot !

It looks like it is working, and if it really does, this will be really fantastic.
This should eventually mean that the sme server can be set up with any firewall combination, network adapters etc.
I will now try to make a framwork for a 1, 2 snd 3 port firewall arrangement, revision zero, based on configuration scripts. The next step after that will be to try to make a simple web interface to genereate variants of those configuration scripts "on the fly", from web.

It works and works, I can set the firewall to anything I want to, on all 3 network segments. I can reboot it and it comes up with the new configuration perfectly working as default (configured from /etc/rc.d/rc.local ).. Great !
