Connecting 2 buildings with one network

Specs: Windows XP Pro

I'm a newbie to WANs and using routers, but here is the problem I'm now faced with and could sure use some step-by-step assistance...

I have two separate buildings on a small property and both have separate ADSL circuits from AT&T that bring in the Internet to each building. (No underground conduit to connect buildings.) The owner has purchased a Cisco WRVS4400 Gigabit Router for each building and wants to set up one network between the two buildings where files and printers can be shared back and forth.

My question is, how do I need to configure each router to do this? Bridging? Never done this before.

Appreciate any assistance you could offer.

Since both buildings are serviced by AT&T, I'm sure they will connect them for you through their lines. It will save you a lot of work & it will be more reliable.

Not sure what AT&T would provide you with that you can't do yourself with the purchased routers.

You do not bridge over the internet. You setup a site to site vpn tunnel between the two offices.

I have not done this with a linksys. I work with Sonicwall's mainly. But according to the manual found here

the units support router to router vpn. There example leaves a bit to be desired since they only mention pc to pc via the vpn not office to office which is what a site to site vpn refers to.

You want a site to site vpn. This connection is transparent to your users at both ends of the offices.

If your buildings are close to eachother, might as well use a long network cable and have 2 or more switches in each building. Don't forget to have 1 or 2 domain controllers in each building as well as well as exchange servers and file servers.
