Re: PIX v7 application inspection, class-maps, and ACL's
Thanks so much for your answer. It makes sense and is in line with some documentation I saw regarding routers and CBAC. I couldn't find anything explicit for the PIX, though.
There's just one more thing that, perhaps, you could confirm for me. I assume that you only have to permit the base protocol port, such as, 5060 for sip. Then the inspection engine dynamically adds the appropriate pinholes to the inbound acl to permit the media streams. Is that correct?
