Has anyone looked into the possibility of a user on a network under
a Firewall running a SLIP/etc connection? Example.
You have a closed 1200+ PC-machine LAN, connected to the Net thru
a BSDI+Firewall. One PC-end user in his days of wisdom decides to
purchase a SLIP-connection to a local INet provider. He enables "IP
Routing" from his Windows for Workgroups, and someone on the net "sees"
or hears about this, and decides to route himself into the "firewalled"
network thru this machine... Boom.
I couldn't think of an easy way to disable this possibility, other
than telling the end user not to do this. Any hints/ideas?
