Come on, everyone. Where are you folks on this one? All you CCNA candidates.
Show us your stuff. All you ACRC students - give it a try. I can't believe
we haven't had a go round about this one.

For the record, I have already filed my answer privately. It is a fun
puzzle, and one that will demonstrate your thinking skills.

Who knows the answer? How do you know you're right????

Puzzle posed by Mike Williams:

Make a (single line) access-list that will only allow traffic from addresses
matching the following model:

x.x.x.1
x.x.x.9
x.x.x.17
x.x.x.25

It's along the same lines as the question you posed, but a little more
challenging since you only want those 4 addresses to pass through.....  =)

My newsgroup reader "claims" to have posted my response to this when it was
first asked.  And for the record, I did have the correct answer and
explanation too =P.  So instead of posting yet another explanation on how to
filter odd/even IP addresses, I'll post a similar but different question:

Make a (single line) access-list that will only allow traffic from addresses
matching the following model:

x.x.x.1
x.x.x.9
x.x.x.17
x.x.x.25

It's along the same lines as the question you posed, but a little more
challenging since you only want those 4 addresses to pass through.....  =)

If you want the answer without me posting it to the whole group (to keep
things fun), feel free to e-mail me and I'll reply via e-mail with the
answer.
