|If I were you, I would setup a dns on your network if you haven't allready, also install the role for DHCP on the server again if you haven't already, im asuming you already did the DHCP if you whole setup works.|
After you have done that set up the modem to hook up to one NIC on your server. Then use the other port to connect to your router. (make sure you disable the DHCP on the router also) This will allow your server to do all of the Connections through the internet.
Under the network connections create a new connection, and choose advanced connection, then selet accept incoming connections, and since you want vpn's make sure you choose that to, set the user permissions, then on the networking software, make sure everything is checked. Then finish the connection.
When this is done you should beable to properly vpn into your network, make sure you turn your firewall on and set it to accept VPN connections.
As far as that set up with not having a physical firewall it is a bit risky, but you should be fine.
As far is your internal network, the connections should automatically pick up from the DHCP from the server. Just make sure you have everything configured right.
