    (ASA 5510)

    I have a web server that everyone can reach from externally, but I can not browse from it to the web unless I use IPs. DNS does not work. I have the DNS on the server pointing to my ISPs DNS servers.

    Is there a certain port I have to open on the outside or DMZ port to allow access to external DNS servers?
