how do I get 2 IP's through 1 router?

[askIllustrator]

I am renting an IP from my cable modem provider in addition to the one that comes with the account. I just upgraded from a hub to a wireless router. The router will share one IP but I perfer one per machine. Does anyone know how to configure a router to let an additional IP through?

You have to activate NAT feature of your router. You use one IP for external(provided by your ISP) and the rest is internal: ie 192.168.0.1 - 192.168.0.254.

What you're asking to do really doesn't require a router. The purpose of a router is to 'route' the traffic on 1 [external] ip address to multiple [internal] ip addresses (or individual computers). Essentially, with 2 machines and 2 ip addresses, you need to go back to the hub scenario (or wireless access point if you want to go wireless). Is there a reason that you need the 2 external IP's?

Why are you doing that? What is the second IP for? Do they have some sort of restriction on the number of devices allowed to operate on your cable network?

Both machines are used for mmo games and I dont want any traffic probs with the 1 ip. For 5 bucks extra a month I get 2. I guess I really never tried gaming with 1 IP but since both machines are usually connected to the same server I'm pretty sure I would notice a difference in performance. I get a slick 1.5-2.5 anyway so maybe I'm ok with one. What do you think?

Unless they are opening up the pipe for your second IP, I would only get the one IP. Some cable providers limit the speed of the users connections.

I think, unless you have something other than a standard cable modem, you would only be able to use the second IP on another cable modem. I don't know of any cable modems that support two IP's.

Besides, you still only have one cable going to your home, right? And, you can run many PC's behind that cable modem. ALso, you can upgrade to a better modem.
