Re: Test Networks Can't See Internet

To get to the A and B sites from the production LAN (and the
Internet) you will need extra static routes on the Linksys router. Its
default route is out to the Internet, so it will not automatically route
traffic for the 192.168.20x subnets to the RRAS routers. You will need to do
that yourself. eg

192.168.200.0 255.255.255.0 192.168.90.6
192.168.210.0 255.255.255.0 192.168.90.5

That should get it working. Traffic to the Internet from A and B will go
first to the RRAS routers then to the Linksys (both by default routing). On
the return journey, the Linksys will forward traffic for the 192.168.20x
subnets to the appropriate RRAS router, which can deliver directly.
