Two IP's / gateway's on one system?

I am trying to setup a system with two NIC's such that it takes up two real
IP addresses. I'm using Gentoo.

So far I have managed to setup the two NIC's to have their own IP address -
that's easy. There is one gateway set for one of the interfaces - also easy.
Let's say the outgoing gateway uses the same interface with an IP address
assigned ending .1 - obviously, anything incoming to .1 would be fine.

Say someone tries to access .2 though (for argument's sake, FTP) - they
attempt an FTP connection but it's unsuccessful. Presumably because the
return gateway is .1 and thus confuses the system?

The question :

How can I route requests to .2 such that they are returned from .2 as well?

Thanks,

- Terence

Thanks - just what I needed.

Was a bit complicated and, at a glance, it makes no sense - but at least
it works. I suppose i'll worry about understanding it later!

Thanks again.

I do not fully understand the mechanism or have two providers to try it
out, hence my lack of comment. I'm glad it works for you.
