... hmmm ... a silly question :

... did you do : echo 1 > /proc/sys/net/ipv4/ip_forward ? ... on your firewall

Yes, of course :-)

IP forwarding is active and has always been (I said that in my original posting), but I still can't access the web server behind the firewall :-(

didn't the proxyarp work ?

I am just looking into that issue. I have found this on the net: http://www.sjdjweis.com/linux/proxyarp/ According to this, enabling proxy_arp on the web server is only half the job. At the moment, I am trying to configure ARP on the firewall. Perhaps you have a quick example that fits my setup?
