- Can anyone help me on this ?
-
- Our Sun installation is connected to the world through a CISCO router
- setup as a firewall. The firewall should keep out all unwanted traffic,
- but I want it to allow mail connections and Domain Name Service
- information to pass freely through the firewall.
-
- If I only knew the protocol and port number(s) used by BIND, I would be
- able to configure the firewall with this information - unfortunately I
- cannot find this information.
-
- So can anyone tell me:
-
- 1. Which protocol (tcp, udp, ...) is used for interchanging
- DNS information ?
-
- 2. Which port number(s) is/are used for DNS information ?
-
- Please respond by Email !
-
- Eagerly awaiting your response,
-
