Hi Steve,
I am actually running the setup below (on LAN# 1) on Dachstein Kernel 2.2.19
based disk image v 1.0.2 and would definitely prefer to continue with it but
would not mind using a different leaf image if advisable. The issues I
raised were because I noticed (if am right) that on Dachstein, I have to
configure which IP is my external IP (single IP) for portfw while and which
internal IP & Port  to forward services to (yet I need two ext IPs and Int
IPs). I also noticed that I specify which is my Int LAN IPs for NAT (again I
only noticed 1 network range space when I need two). **Am assuming I will be
using portfw to forward smtp & http for the two domains to their respective
mail and webservers.

These were the reasons coupled with the fact that I had tried multihoming on
either interface e0 and e1 without success.

Any suggestions with examples based on my initial setup below would be
highly appreciated.
