Server 2012 configuration

Good afternoon;
I am configuring a server for a friend of mine and his SOHO.  I previously configured ADDS and print/ file sharing.  They are now interested in VPN remote access to the domain.  They have purchased a static IP address for the server and I am attempting to configure it.  When I simply input the IP, gateway, subnet mask and DNS addresses the internet connection is not behaving properly anymore and workstations are no longer connected to the domain.  I want to be able to leave their domain alone for the most part as their shares and user/computer settings are how they like.  I also want the workstations to be able to continue getting their dynamic IP addresses as they previously have.  Do I need to install and configure the DHCP role on the server to provide the 1 IP address to the server?  There is only the 1 server I am slightly confused at this point and any help will be greatly appreciated.

they can use the vpn that is supplied by their router or you can install the routing and remote access role (rras) to provide the vpn.

The server should have a staic ip address in the range that the router supplies. (don't forget to configure the router to let it know that that ip address is static and the mac address of the server)

Thank you for the response, the root of my problem and confusion was that the IP they told me it would be was not the IP address that had actually been assigned.  Go figure!  Thank you for the additional information of being certain my router is configured properly for the static IP.
