I take it you want to do something like this?
Keep in mind your other 2 routers are doing nat I take it?
Keep in mind while your 2 downstream network would be able to get to anything they want on 192.168.0 in such a setup - if your going to put devices on that network.
1 couldn't get to 2, and 2 couldn't get to 1, and 0 wouldn't be able to get to 1 or 2.. Without setting up port forwarding on these other routers.
I would never suggest such a setup.. But if if that is what you have to work with until you get a new pfsense.. Yeah it can work.. It's a mess, but sure it can work.
