Our company and another company in the same building need to share
200mb+ files on a daily basis. We are close enough to run a few cables
between the lans but we want to maintain security by limiting access
to a single file share or 1 share on each network and keep our own
Internet routers, dhcp servers, running.  We each use soho routers
(Linksys & Netgear) with no dmz ports on them. I was thinking of
purchasing two more soho firewalls and connecting the Lan interface on
each one to each of our Lans and adding static routes on our current
routers to route traffic to them. I would then have two options. 1)
connect the wan ports to a hub and plug a server into the hub. 2)
Configure a VPN on each firewall so that any traffic covered by the
policy will automatically be routed to the other network. I would
prefer option 1 because it seems to isolate both networks better than
2. I don't know if any of this will work. I'd appreciate your input.

thanks
