I have had Server 2012 set up for quite some time. It was working fine till last week when I was having network issues, and removed the LAN network card to check it's operation.
When I reinstalled it, RRAS was gone. This machine was being used only as the local network domain controller, AD, DHCP, DNS and NAT. It was used for nothing else.
The active directory security port is blocked by an external firewall (there's been a lot of DDoS activity through the ISP, and they refuse to block that port themselves).
The server has 2 NICs, one for the LAN, the other to the firewall. Now I am stuck with a domain profile on the firewall/internet side, and can't get rid of it. This makes it so I can't re-establish the NAT portion of the DC.
Is there any way to reinstate this? If not, what's the suggested architecture of the network to allow the firewall/router to handle NAT, but the DC to handle everything else?
BTW, I can access internet from the DC, but not from any LAN connected systems, but I can access any LAN systems, including the DC from anywhere on the LAN. It just won't pass traffic through the DC to the LAN.
Any help on this would be appreciated.

Found a roundabout way of enabling NAT only through RRaS. Wasn't easy to find, but all is working now.
