Multiple DMZ Routers?

A friend of mine needs to give 2 PCs access to a DMZ on his home network. However, Linksys routers only allow the option of assigning one IP address into the DMZ. What are his options?

I believe Linksys had stated that multiple DMZs would be available via firmware at some point, but obviously that hasn't happened.

SMC had a Router that can do 10 DMZs you might be able to find it around for less than $50.

I think it was the SMC 7004VBR

I think the term you're referring to, DMZ, is diluted from its original designation. From what I have experienced, most of these routers define a DMZ as a 1:1 mapping between the external IP address that is acquired (usually) on the WAN interface (or PPPoE interface) and this designated internal IP. Obviously, it has not created an additional segment that is actually de-militarized as they rarely have the capability to do this, nor is it in high demand for their target market segment.

This being said, in order to do a 1:1 .. n:n mapping, would you not need n WAN IP addresses?

Good point. I doubt he is using more than one IP from his provider.

Perhaps all he really needs are a few forwarded ports? Not many applications need a 1:1 mapping to work properly. Does he need two similar parallel services that cannot operate on different ports by chance?

Yeah, turns out all he needed was exactly that...a few forwarded ports. I convinced him that having his systems exposed to the Internet was a bad thing. :)
