Hello, I am trying to setup a VPN server behind a Linksys WRT320N router and am having little success. I have the server in DMZ and all VPN passthrough enabled, all firewalls are turned off and im trying to connect from another location outside the LAN using PPTP with a computer on the DMZ aswell and no firewall. When setting up RRAS choose Custom and only check VPN server. Both network IPs are in the192.168.1.xxx range however in the routing RRAS properties on the IPv4 tab i have the address pool set in the 10.1.10.xx range becuase i read that they cant be the same. Im using Windows Server 2008 R2 with the 180 day trial. Ive been using and working on computers for most my life but im very new at doing somthing like this and have exhausted myself trying to make this work and i have run out of ideas. Any suggestions are greatly appreciated

If you are behind a router, the VPN server only needs one NIC. Giving a RRAS server two NICs in the same subnet will cause you grief. You only need two NICs if the server is directly connected to the Internet (one NIC public, one private). If you are behind a firewall/router you need only the private NIC. The remote user connects to the public address of the router/firewall. You extend the VPN connection using address mapping or port forwarding. Disable one NIC. Check that you can connect by VPN from a LAN machine using the server's LAN IP. If that doesn't work, check your RRAS setup. There is no point in going any further until you have that right. When you can connect locally, configure the Linksys to forward tcp port 1723 (for pptp) to the LAN IP of the RRAS server. You should now be able to make a VPN connection from a remote location using the router's public IP address. Bill
