Access list doing the same thing

[insccisco]

Hey guys, I have an access list which is applied to the outside interface. There are 2 lines, however that I think they might be doing the same thing and I want to know if I can get rid of one. They both get hits though when I do a "sh access-list 110"

access-list 110 permit udp any any eq isakmp

access-list 110 permit udp any eq isakmp any

thanks

For light reading, I usually hit the IOS configuration sections

For your query, I would suggest reading the security section from the link above.

I heard good things about this book as well:

thank you very much. They look good for reading. The book also sounds good enough that I will buy it, although it has lots of errors according to amazon reviewers, but overall seems like a good beginner's book

thank you again Edison

You should give it a try, it's a good read. The author has addressed the errors on the errata:
