Command
1. Enter system view. system-view
2. Enter interface view.
interface interface-type interface-number
3. Configure an internal server based on
ACL.
nat server protocol pro-type global acl-number inside

60BConfiguring DNS mapping
With DNS mapping, an internal host can access an internal server on the same private network by using
the domain name of the internal server when the DNS server resides on the public network.
To configure a DNS mapping:
