Draytek 2820 Lan to Lan VPN. SBS2003 R2 Std domain with 2 nics to multiple xp sp3 clients.
Posted on 2008-10-30
I have a user with a main office which has 5 computers connected to an sbs 2003 domain (internal nic 192.168.16.1 / 255.255.255.0, and external nic 192.168.1.2 / 255.255.255.0, (gateway) router address 192.168.1.1). I am using the SBS for firewall and DHCP and all computers can access internet and email etc fine through the Draytek 2820.
I now need to connect a branch office which has 3 computers connected directly to another Draytek 2820 via a different ISP (there is no server at this office). I have been trying to setup a Lan to Lan VPN with the routers and can get the routers to connect fine, but I can only ping the lan on the public side of the sbs server - i.e. I can ping 192.168.1.1 and 192.168.1.2 from the branch office, but cannot ping 192.168.16.1.
The lan to lan setup in the routers is as follows. Main office - Dian-In, PPTP, TCP/IP settings My WAN IP 0.0.0.0, remote gateway IP 0.0.0.0, remote network IP 192.168.2.0, remote network mask 255.255.255.0. Branch office - Dial-Out, PPTP, TCP/IP settings My WAN IP 0.0.0.0, remote gateway 0.0.0.0, remote network IP 192.168.1.0, remote network mask 255.255.255.0.
I believe I need to setup a static route either in the router(s) or RRAS in SBS, but have tried various configs with no success. Can someone please point me in the right direction or suggest another setup which may work?
