Rory, you need to look at L2TP and then possibly EOIP in the tunnel. This would keep your subnets intact. Just create a netwatch to check the wireless link and when it fails fire up the L2TP client to 'phone home'.
-- Regards Hilton J Ralphs Think Technologies -----Original Message----- From: Rory McCann p How would I want to go about setting this up while keeping the same network topology intact without having to re-subnet and/or break up my broadcast domain? I already have a PPTP VPN solution in place that assigns IPs on a different subnet and the MT at the main office handles the routing from that point, but that is about as far as I'd want to break it up. _______________________________________________ Mikrotik mailing list Mikrotik@mail.butchevans.com http://www.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
