I recently rebuilt all my bind servers to verison 9.1. No one however can do a reverse lookup on me, all other lookups are fine, and internal I can do reverse lookups. I added a line in the named.conf file to query on just port 53 and port 53 is open to my entire network. Can anyone think where I am missing something? Or is there another port I should open. I understand that when I leave my machine I leave on a high port and to go the known port, and vice versa coming back. When does it get to the known port, once it is on the wire or once it gets to the end machine? Thanks for any input.
