Easiest way I know is to use NAT on the router. (See Cisco's paper on
NAT) Since this is a leased line and you own part of the company I
would think the security issues should be somewhat diminished. I
wouldn't
put out the money for a full blown firewall. I'd use NAT and the
filtering capabilities on the router to handle it.
The NAT capability can be added to a Cisco 2500 series router for as
little as $1,000.
