Keep same LAN IP over VPN

We have four office locations that we need to VPN together all of them have NS5GT Firewalls. What we want at all four location is the same LAN IP scheme.

For eg; 10.1.2.x scheme

All locations have static WAN IP. What kind of VPN would be recommended and if possible steps to implement them at all four locations.

Thanks

Why do you want the same subnet at each location ?

We would like to share resources at each of the location like printers/servers so on and so forth and would like all of them to have the same IP scheme at each location making it one big VLAN.

Not a good idea even if you could even get it working, which I doubt. A different subnet at each site like 10.1.2.x 10.1.3.x etc all subnetted to a class C 255.255.255.0 is the way to do this. Whatever VPN device you choose will be able to route between the sites. If you got it working then the broadcast traffic would swamp the wan links anyway. simon

Simon,

Thank you for your response, what kind of VPN would you recommend between all these four sites, the major application we require to access on all the location is pretty huge and runs off of an extensive oracle database. So we need to maximize on the T1 bandwidth, would you recommend site-to-site VPN policy based or router based, or any other form of VPN?
