What is the threat that they are trying to protect against? Usually with
frame, it's worry that the frame provider will have a malicious employee,
or screw up the config, making the frame network no longer private. The
solution to that is to VPN across the frame links.
What you're talking about implies that there is no trust between the
various frame endpoints, though. Some sort of partner network, perhaps?
If that is indeed what you want, then if the firewalling features of your
router won't cut it, a Nokia isn't a bad router for a firewall...
I don't know the answer to your in-and-out routing question.
