my isp offers 2 ip addresses, but how do i assign each pc with it's own?
right now i have 2 computers sharing a connection using a linksys router. the router assigns ip addresses to both of them. and i guess it "takes in" an ip from my isp.
however, my isp offers me 2 ip addresses and i was wondering how i'm going to use them, so that each computer has it's own ip that's not from the router. or is this not possible?

If you plug both PCs and the cable modem into the regular switch ports on the router, you should be able to use both IP addresses just fine. But you lose the protection you get from NAT on the router. And I can't see any potential gain for you.
If initiated from the internet and inbound, NAT can cause some problems.
If the packets are always the same type (FTP, ICQ, whatever) and always for the same PC on your LAN, you can set up "port forwarding" that basically tells your router that any packet destined for port 20/21 (for FTP) is to go to a particular PC at your place.
Similar trick for running a game server on your LAN - just probably more ports involved.
But you do have a point. If you need to have packets originated on the internet/WAN that may be intended for more than one PC at your place, you would need to maintain seperate assigned IP addresses and a router with NAT wouldn't work for you.
