routers

hi, my question is what exactly is a router? Ive got 2 computers here both equipped with ethernet NICs and if I get broadband, can I use a router on them? Do I need 2 IP addresses for 2 computers on a router, or does the router do the same as ICS/NAT software? Also, if the router only need 1 IP address, how would it know…

hi,

my question is what exactly is a router?

Ive got 2 computers here both equipped with ethernet NICs and if I get broadband, can I use a router on them?

Do I need 2 IP addresses for 2 computers on a router, or does the router do the same as ICS/NAT software?

Also, if the router only need 1 IP address, how would it know which computer to send incoming connections to?

Thanks,
andrew

It would use NAT

No i get what ya mean, as far as I know, NAT will handle connections with the outside world. When it receives data, it somehow knows what internal IP address it belongs to and will route it to yourself. Only prob is that it prevents some end to end services, not sure what off hand.

Try:

www.howstuffworks.com
www.google.com
www.dslreports.com (has some stuff about routers I think)

I've some other links in the FAQ.
Also the Linux howtos on NAT are pretty good and should explain it.
