ZBFW simple question

Hi,

 

It's very basic question but I would like to be sure because I didn't find a clear and simple answer.

When I setting up a class-map to inspect traffic (match-any) I need to choose which protocols to inspect but do I understand this correctly if I will set:

#match protocol udp

does it apply to for example DNS packets which also use udp or I need to define match protocol dns separately?

Hi,
Yes, by matching on UDP protocol it should permit DNS, unless of course DNS is using TCP.
