Public IP forward
Posted on 2004-04-06
Is it possible to forward my supplied public IP's from my 1720 router - through a Cisco PIX506E - to my hosts in the DMZ? So it doesn't need to be natted into private IP's? Currently my ISP forwards me a block of 32 IP's, which are on a different subnet than their gateway and the outside interface of my router. I have the first forwarded public IP on the inside interface and the rest go to the websites, proxy server, etc. I just want to put a PIX in between but not lose the non-natted setup.
I want this:
Gateway from ISP ----------> Outside (1720) Inside --------> outside (PIX) inside ----------> hosts
66.XX.XX.1 66.XX.XX.2 66.XX.YY.94 ????? ?????? 66.XX.YY.65 - 93
they forward 66.XX.YY.64-95 forward 66.XX.YY.64-95
If the PIX is not equipped to do this, would another router be able to and how?
