Linking Two Offices

What are a few top ways to link 2 office locations together so that office employees can share network resources relatively seamlessly.  Since I am linking 2 businesses, reliability and security are highly mportant factors. A VPN connection which requires use of software like PC Anywhere is less seamless that I would like as it requires establishment of the VPN connection and then running of the PC Anywhere app, etc.  Both offices have DSL internet connections and both are running peer-peer networks, so they have no outward facing NIC's.  Currently both are running NetGear FWG114 routers which I believe offer some kind of router to router connection, but I need to look into this more.

The VPN you are talking about is client to server VPN and probably not what you want.

You can also use site to site VPN where the routers on both ends establish a VPN connection and link both internal networks like they were one. You can then access resources on either network like they were local.

Look at this document.

Hi billrush2,

brakk0 is correct in that you want a site to site VPN utilizing your existing Netgear firewalls.  The below is an excell Netgear resource in configuring site to site VPNs.

With a site - site VPN, how do the network resources look to users?  In other words, when site a goes to a client PC and pulls up 'network places' (Win XP) do they see all pc's in both offices just as if they were all in one location.  If not, please describe.

Yes, as long as you have DNS or WINS servers set up on both sides. Even without those, you can go to start, run and type in \\computername or \\computername\sharename.

Can you point me toward more info on this?  I need to have the ability for everyone to be able to view all network resources.  Since each site is P2P, there is no domain or domain server currently.

You could do a wireless backhaul using redline hardware, I think they are capable of doing 35mi with two devices.

How tall are the office buildings?
