We have Gauntlet for our internet firewall, but a question came up the
other day because of the location of a particular site and costs.

How secure is Cisco IOS for connection to the internet purely to provide
VPN tunneling to another one of our sites. Neither end would be
permitted internet access through those routers, only access to the lans
on each side.

I realize there are issues of reliability and performance with such an
arrangement, but that's a tradeoff we can evaluate. I have never wanted
to depend on a router for a "firewall", but this is a bit different.

Comments?
