I've been asked to setup a site to site or LAN to LAN link via a broadband VPN link. I'm a little confused as I'm unsure of how to IP the LAN's at each end of the link.
Would the LAN's need to be in the same sub-net or could they be in different subnets. I'd prefer them to be separate subnets as I have an Active Directory at each end and to allow for local authentication they need to be in different subnets so they can identified in sites & services.
Any info or links would be very welcome. I've been provided with Zyxel 662H adsl routers
