We have to connect our enterprise network with another corporations
enterprise network (not the Internet)

Here's the scenario:

1) Inside workstations/hosts need to use their own network addresses
2) Inside workstations (600+) need to connect to outside hosts
3) Outside hosts will only allow connections with machines in it's own
address space
4) There are a handful of inside hosts that the outside hosts need to
communicate with (with outside static IP addresses)

The main concern is that I don't want to burn 600+ addresses from the
outside network to translate 1-to-1 when only a few of the inside hosts
need static IP addresses.  What I would like to do is translate the
inside workstations outbound connections to 1 outside address (like I
currently do with the Gauntlet firewall we use for the Internet) but be
able to give the internal hosts a static address in the outside address
space.


Question:

Which vendors offerings can meet the above criteria?
