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?
You need to set up DNS so that the dynamic IP address assigned internally resolves to a hostname that your system likes. It may be sufficient to do this in the /etc/hosts file.
We use split-horizon DNS with djbdns to allow internal resolution of private subdomains and reverse DNS for the local private net blocks without broadcasting this to the world.

A child can go only so far in life without potty training. It is not mere coincidence that six of the last seven presidents were potty trained, not to mention nearly half of the nation's state legislators. -- Dave Barry
