Take a close look at your logs...sounds like you might be on a cable-mode
(or other shared-network setup).  The denied packets are probably being
generated by one of your 'neighbors', and are coming in your external
interface, otherwise they wouldn't be getting logged...

Probably, although you don't mention what you're trying to specify source
ports for.  If you need to make custom rules, that's what the
ipchains.input, ipchains.output, and ipchains.forward files are for in /etc.

Yes...simply cd to the directory you want the package extracted to, and run:

zcat </path/to/package.lrp> | tar -x

Or any one of the several equivelant methods to un-tar-gz a file...

Probably, but it would take a lot of work.  Are you volunteering?
