On my logwatch that I have emailed to me,
I see a line where I'm showed logging in via a known
ip address, and when I log in from my laptop through
my EV-DO card wirelessly, the computer show log in as
ok, but it can not translate the ip from the aircard
and marks the log in as a possible hack attempt.

How do you go in and set a network subnet as a valid
ip block and not an attack attempt?

Thanks,
