Also, you want to create a secondary IP not a sub interface. With a sub interface you'll have to enable tagging, etc, etc. You can add a secondary IP to your current Ethernet interface on your router by doing..

Let's say you have multiple networks that physically connect to one interface. Really all you have to think about is that each IP alias tells the OS to treat each alias as it's own network interface. You can google subinterface or NIC alias and find more information. A couple things caught my interest in your reply to our answers. You shouldn't have to add arp entries manually, and if you do, there should only be a few of them. If you're still not using "Client side NAT" in global properties, then I'd suggest looking into it. This will save you quite a bit of time. Another thing that caught my interest was the fact that you'll need to re-gen your licenses. I'll be the first to admit that I don't know whether or not it's ok to license your firewalls to internal IP addresses, but when you contact account services, I would make sure that you're using centralized licenses, and if not, I would license them to the internal IPs so that you don't have to regenerate licenses in the future.
