what you're calling the gateway is the firewall--the only host that your
router allows packets to reach.

it'll work fine for you...and everyone else. don't allow folks on
the internet to access nfs on your internal net.

it's easy enough for someone to spoof your us office network and
drive straight through your router as well. this *is* a good
problem. does anyone have any good solutions?

i haven't been able to decide what to do with this and hope to hear
more response from the list. add users to the firewall, and you add
too much noise to the logs for them to do any good, as well as
adding to the vulnerability of the firewall. have all users go
through a single account and you have a password distribution, and
unfortunately, there is always a tradeoff: the better the security,
the more inconvenient the firewall. is a convenient, secure
firewall desirable? attainable?
