No problem.  Simply take a Linux machine with two interfaces, and plug
one into each network.  Assign IP addresses to each interface, and
enable packet forwarding on that machine.  It's now acting as a
router between them.

Now you just have to tell the 35 machines on net1 that any packets
destined for net2 go to the IP address of the Linux machine's
interface on their network, and the converse for the machines on

Or, if you have a router that's acting as your default gateway
(connection to the internet most likely), you can tell it to
do the forwarding so you don't have to change routing on all the
other machines.

 ISA isn't dead, it's just that people wish it were.  The correct term for
 this condition is "legacy"...  --  Sean Reifschneider, 1999
