Whoah, there Mike: 1) he probably has the 5 IP's assigned right out of the bridge group, not a routed subnet. Some ISP's do that sort of icky stuff. 2) if they are out of the bridge group then he can't use them as a routed subnet like your advising. 3) You most certainly can shut off NAT on the Linksys and use it as a regular IP router. We have several customers set up this way. 4) The stinksys will not work with what he wants to do because a) it can only do 1 IP number per interface and b) it's NAT is ONLY many-to-one, you cannot do static maps. 5) Windows (which is running the IIS he has) NT does NOT appear to arp on secondary IP numbers assigned to it's interface. (at least it never did it for me) It only ARP's on the primary IP number. Thus he cannot simply plug it into the DSL bridge and get his multiple IP numbers "routed" to the IIS he has there. I assume he's discovered this. Further discussion on this is probably going to lead nowhere in the absense of IP numbers and subnet masks and such, even ficticious ones. You and I are both guessing at his network topology. Bob, would you please be more specific?
