12 years as a firewall guy... and this is a first for me.
I have a request to allow firewall access to an app that apparently uses tcp port 0. I thought it didn't exist... but good-ol' google proved that wrong. I did find this comment: " Port 0 is officially a reserved port in TCP/IP networking, meaning that it should not be used for any TCP or UDP network communications. "
Just out of curiosity, anyone implemented an acl using port 0 before? Any issues on the ASA side?
Thanks,
Mike
