This much I assumed. Yet in setting up static routes it's not working.
Thus my inquiry as to setup guide info for this sort of thing. If it CAN
work then it must be some missing configuration. Either on the RRAS box,
the segment routers or both. I don't expect to hash it all out here, just
trying to find links to docs online.

The root of your problem is the two Internet connections. That is, I mean,
each LAN has its own.

Using a design with single RRAS box between the LANs assumes there is only
one Internet connection. In that model each LAN uses the RRAS box as their
Default Gateway,..and then the RRAS box uses the Firewall as its default
Gateway. It all works fine & dandy when there is only one internet
connection. But it fails in your case.

Since each LAN has their own internet connection you have to work it like
there is a WAN connection between the two LANs (even if it isn't really a
WAN).

What is a WAN connection like??? Well it has two Routers,...one on each
end of the WAN link,...meaning each site has their "own" router. So how do
you do it here?? Well you have to use two RRAS boxes with a /30bit network
(a 2-host network) between them.

Like this:


[Internet] [Internet]
| |
<firewall #1> <firewall #2>
| |
[LAN #1]----<RRAS #1>---<RRAS #2>----[LAN #2]


1. All Host on LAN#1 use RRAS#1 as their Default Gatetway
2. RRAS#1 uses Firewall#1 as its Default Gateway
3. So RRAS#1 is the primary routing "decision maker" for LAN#1

4. All Host on LAN#2 use RRAS#2 as their Default Gatetway
5. RRAS#2 uses Firewall#2 as its Default Gateway
6.So RRAS#2 is the primary routing "decision maker" for LAN#2

7. The two RRAS boxes either use Dynamic Routing Protocols (like maybe RIP)
so that they "know" how to get the traffic to the correct LAN between
themselves. If you don't want to use Dynamic Routing Protocols then a
couple Static Routes should work.
