I don't have natd configured in the slightest. My assumption was that I
didn't need to run it because I have a router assigning the IP addresses and
doing NAT for my cable modem, while my university is assigning me an IP
address for the second interface. Maybe I do need to run it. Can someone
point me in the direction of an install guide, or quickly explain it - the
man page confused me half to death.
Also: what was that information about having natd on both interfaces? I know
that's nonstandard, so how would you configure that?
It's likely that setting up a route for the university subnet on the client
machines, via routed, or on your routers which points to your university-bound
interface would help.
At one point, when I was going some experimentation with sendmail, I got a call
from the senior admin at CMU, who asked for me by name and immediately asked me
to pull my ethernet cable out of my computer because it was generating about 50
bounces a second to <[EMAIL PROTECTED]> in a mailing loop.
I mention this because if you enable natd in both directions, you are probably
going to loop university traffic out your cable connection, and vice-versa for
Internet traffic in via your university's network, bypassing their firewalls
and security in the process.
Before you get a call from some senior admin who is not going to be thrilled to
solve an emergency on a Saturday, I suggest you stop for a second, figure out
what you actually need or want to do, and be prepared to discuss it with your
university admins beforehand and get their advice.
