One thing you could do would be to keep the 192.168.1.0 addresses on your
internal network, and then add all four of the real addresses from your ISP as
aliases to the gateway box. Patch your kernel for IP port forwarding, and use
ipportfw to control what services of your internal machines to expose to the
outside world. I have a similar setup, and it works great.
