I have been assigned two static Class B IP addresses from my ISP, but I only have a single physical cable coming in. I would like to build 2 independent firewalled networks. I'm very inexperienced in NAT and would appreciate comments/suggestions/alternatives on how I have envisioned this to work. Many thanks in advance.
