Routing Multiple Inbound IP Addresses -- How?

[Janina Sajka]

This is fairly basic, I'm sure. But, for the life of me, I can't find
documentation on it.

So, here's the situation ...

I have several routable IP addresses. All of them need to come through
the same interface, over my DSL to be specific. So, how can I route
based on IP alone? I know how to route by port, but how do I do it by IP
address?

All examples/help much appreciated.
