At some point in the future, I'd like to add a third, but I'm a bit puzzled as to how it will work. First, I'm divvying up 192.168 like this: 192.168. 0. 0 / 24 ppp links 192.168. 1. 0 / 24 network #1 192.168. 2. 0 / 24 network #2 . . . So, in order for network #1 to connect to network #2, a ppp connection is initiated with network #1's FBSD machine having its IP address 192.168.0.1, network #2's FBSD at 192.168.0.2, and routes setup up for 192.168.1/24 through 192.168.0.1 and 192.168.2/24 throgh 192.168.0.2. Here's the question. I know I can just add the third network and pick one of the two networks to be a pass-through; for example, network #3 would reach network #1 through network #2's FBSD box. That's easy. But annoyingly limited bandwidth forces me to think otherwise. What's the best way to handle this without sucking up IP addresses in 192.168.0/24? (i.e. if I kept going like this, each host would have two links with unique IP's, making 6 IP's used for 3 networks.) Can I reuse IP's?
