DNS through Firewall

[Gary Wardell]

Hi,

NAT doesn't prevent someone from attaching my FTP server and trying to hack it.

A packet filter can.

But maybe I was a little to quick to speak.

Of course by your definition even an originate only modem could be considered a firewall since it blocks unauthorized access by not
answering incoming calls.
