I have a D-Link DGL-4500 and I've been using that for a long time as my DHCP server. I now have a Windows Server 2008 R2 machine plugged into it and I have set it up as a DHCP server.
I don't have 2 NICs on my server machine, so I still wanted to use my router as the main hub where all of my machines connect. The only thing I don't want the router to be anymore is the DHCP server, but I still enjoy it as a firewall.
Is there a way I can use plain old port forwarding or something similar in my router to forward DHCP requests from computers connected to it to my Windows server? My router doesn't have a "DHCP Relay" feature that I can see, I only have the ability to turn the DHCP server on my router on or off.
Help is greatly appreciated!
