Subject: Access list
> I've spent the entire afternoon on a single access list and still
can't
figure out the logic. I've looked up articles, and converted everything
to
binary and still can't make sense of this.

> Given the following networks (last two octets relevant), I need to
block
them all in as few lines as possible. Some of you people can do this in
your
heads. Simpletons like me, however, can't.

> 1.2
> 1.10
> 1.18
> 1.26
> 3.2
> 3.10
> 3.18

statement, but I need specific deny statements that only apply to the
networks to be blocked and to none else.
