Subnets and static routing

[Bob.]

I have several subnets in my network. All subnets have their own router with an assigned IP (i.e., 192.168.x.1).

I have my reasons for isolating the networks, but from time to time, it would be convenient to access systems behind some of these subnets. I know I can create static routes via my main router to do so. Does creating these static routes defeat my purposes of isolation (i.e., reduce security to pre-subnet levels)?

In my main router that connects to the cable modem (and to which the other routers are connected via the LAN ports of the main router), if I create static routes for the subnets I wish to access, how does this affect the isolation factor? Will communication be one way? Both ways? Or will it basically cancel out the the isolation (security)?

I hope this isn't too convoluted. I'll clarify if needed.

Thanks,
Bob.

You can install VNC Client and Server on all computer, or other combinations to you liking.

Ultra VNC has DSM encryption to provide high level security and the server can be load as a Service.

It is free for personal use and highly dependable.

Do Not forget to open the local port for it.

Well the big question would be, what is your reason for isolating them? If your intention was to create no communication at all between them, then it probably isn't a good idea to have communication routes on your router for them. The main thing I use subnetting for is to cut down on the broadcasts created and to create more logical networks from one department to another. As far as security and such, that's why firewalls are in place.
