[thelist] OT? IP masquerading with dynamic IP help?

[Colin Mitchell]

I've run this configuration many times now without much problem.  The only
thing that should be different from a static IP setup is that you'll want to
grab your new IP address with DHCP.  At that point, you'll be able to hit
the net from the linux box, an the config for the internal network shouldn't
need to be changed at all.

If you need more than that, let me know and I'll see if I can get you
something more specific.

Hello folks

I haven't had luck finding a clear tutorial or help file on using IP
masquerading with dynamically assigned IPs. I want to share a DSL line
with three computers. I have an intel box running Linux RH 6.2 which I
previously did this with with a static IP, but I've switched to a
consumer DSL line with a dynamically assigned IP and I can't see how
that's going to work with the current setup.

I've looked over David Ranch's tutorial (which I used originally to
setup the IP masquerading with static IP) but he doesn't say much of
anything about dynamic IPs, except a link to trinityOS stuff that I
can't seem to understand or even be sure I've found the right thing.
(BTW, I'm not a complete Linux newbie, I've run RH 6.2 for a year or
more, but I've learned what I've had to do, not a general introduction
that might stand me in better stead.)

Can anyone help? From what I can tell I would have to rewrite/rerun the
firewall script each time I get a new IP on the gateway - surely there
is a better way to do this?

The setup is PII 333/256Mb, two interface cards.

any ideas?
