I have 2 Windows 2003 servers at 2 different offices which are 3 miles apart. The users for these offices rotate on a weekly basis. I want to setup AD replication between the 2 servers via internet connection so that logon passwords and permissions will be the same at each office. Currently, if there are user changes, I have to remote in to each site to make changes which sometimes is time consuming.
I have file sharing setup using an open source VPN called OpenVPN between the sites and this works ok.
However, I'd like to replicate the AD between both offices via OpenVPN or Microsoft VPN (PPTP or L2TP). Both offices use DSL with static IP. NAT is applied at a Dlink Wireless Router/Firewall at each site.
I know I have to set up 2 sites in AD for each office on each Server, however, because I want to do the replication over VPN, I'm not sure of how to setup the DNS or routing. Any help would be appreciated.
