Site to site VPN routing issue.
I'm having some trouble setting up a site to site link between two schools and would be very grateful for any pointers as I'm a bit stuck.
SETUP: Firstly, both sites are on SWGFL and we've had the required ipsec ports opened at both ends. Cisco routers at both ends are managed by SWGFL.
We also have a pair of Cisco SA540 security appliances which have now been configured as a site to site link, this is up and running (states connection established at both ends).
Multiple 2008 R2 Servers run as DCís at both sites (DHCP/DNSÖ) currently RRAS isnít running on any of the DCís.
QUESTION: How would I go about routing the correct traffic though the VPN so I can setup one site as a child domain? Am I correct in assuming adding a static route on the DCs could be the answer? My other thought at the moment is to put a change request in to SWGFL (ISP) and get them to add a new route in to both routers, Iím a bit lost on this one though.
Any help would be most appreciated.
Thanks in advance,
