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.
>
> These are the networks:
>
> 1.2
> 1.10
> 1.18
> 1.26
> 3.2
> 3.10
> 3.18
> 3.26
>
> In binary it looks like:
>
> 1 2 00000001 00000010
> 1 10 00000001 00001010
> 1 18 00000001 00010010
> 1 26 00000001 00011010
> 3 2 00000011 00000010
> 3 10 00000011 00001010
> 3 18 00000011 00010010
> 3 26 00000011 00011010
>
> What do I do after that? I know how to summarize them all into one
statement, but I need specific deny statements that only apply to the
networks to be blocked and to none else.
