Topic: DHCP relay question

The content of this topic has been archived on 7 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have a situation that I am at a loss how to implement, or if it is even possible.

My ISP allots 3 IP addresses assigned by DHCP.  I have 7 computers in the house using both wireless and wired connections.  Would it be possible to have 1 ISP IP address asigned to the router, then to have 2 of the ISP assigned DHCP addresses relayed through the router to 2 specific MAC addresses, while ALSO having the other computers be assigned by DHCP from the router?  (I would then make one of the machines with a router assigned IP address the DMZ, so it would be like having 3 external IP addresses.)

If this is possible, can anyone explain how?  (Without using two routers?)

This post explains how to do something similar to that.

The discussion might have continued from here.
