Hi everyone.
I got a few replies to my earlier post, concerning my need to figure out a
way to route everything coming in from 1.0.8.0 (found behind eth0) to a
router 1.0.0.162 (behind eth1). thanks for your help, but sadly the problem
is not solved. I tried rinetd but that doesn't work for this situation,
apparently. and like i mentioned before ipfwadm isnt good enough, because i
specifically need to route all packets from 1.0.8.0, no matter what their
designated destination, to 1.0.0.162.
I would REALLY appreciate ANY help on figuring out how to do this. If i
can't figure out how to do this within a couple days it means that i'm
going to have to start doing a whole load of things differently at work
which means a whole lot more work because i cant figure out this seemingly
simple problem.

i'll explain the exact set up, in case i've just overlooked some blatantly
obvious better way of doing it. feel free to stop reading and delete this
if you're already bored. basically, theres a linux box that acts as a host
for several small/medium networks. for some of these networks it is an
internet gateway, for others not (usually because they have another gateway
elsewhere). now, i've hooked up a portmaster to accept dial-in access. that
portmaster can assign IP numbers to the callers in order to separate the
users of different networks. for example, network A and B are both hooked
to my linux box, and both companies want dial-in access. the idea is that
the portmaster supplies, for example, 1.0.8.0 IP numbers to callers of
company A and 1.0.9.0 IP numbers to company B. then i need linux to simply
check whether the packets are coming from 1.0.9.0 or 1.0.8.0, and feed the
packets onwards to the correct companies networks. so far so good, this i
can do with ipfwadm, but the problem arises due to the gateway business.
company A has their own internet gateway and i cant let them hog up my
linux box's bandwidth, so if any packet comes from the portmaster with for
example destination www.linux.org, i need it to get fed to network A, not
to my internet connection. ipfwadm doesnt allow this level of versatility.
so you see, if i cant figure out how to do this, it means that i have to
start setting up separate linux boxes/portmaster for every damn network
that wants dial-up access, which would be quite expensive and silly.
please help! how can this be done? how do ISPs do it?
