connecting multiple lans

Specs: Windows XP
Here's our setup...two locations...each
location with its own servers providing DHCP,
DNS, and each with its own internet
connection. They are currently connected via
VPN. We wanted more speed between the two
locations so had a local ISP put a fiber
point-to-point line between the two. There's
no protocols running across it yet. If I were
to plug both ends into a switch, it'll pass
traffic like everything was on our network.
Each location has a firebox firewall. What we
want is to setup the point to point to still
maintain the two networks (ie, DHCP running
on both sides, each location uses their own
internet connection, etc) yet still be able
to pass traffic to the PCs like we do now via
VPN. We were told to just put a $50 Linksys
router in place and that would route the
traffic and block DHCP...sounds easy enough
however I'm not totally sure how to configure
the router to let it work that way. Any help
would be greatly appreciated.
Thanks in advance

You would need to bridge the lans not route between them. They need to be in the same ip subnet. You would block dhcp requests at bridgeheads.

Reason is you can only have one gateway entry. If you want internet it has to be the gateway entry.

kind of hardware am I going to need for this?

Cisco comes to mind but I don't work with bridges. This may help in your search

Ideally you would just place a switch at each end. But switches don't block dhcp requests which is a requirement. Well a L3 switch can but those are expensive.
