How to Configure DNS on ASA

November 1, 2010

Step 1:
Enable dns service on the inside interface
ciscoasa(config)# dns domain-lookup inside

Step 2:
Define dns servers:
ciscoasa(config)# dns name-server 4.2.2.2 4.2.2.3

Step 1 must be done before step 2, otherwise it will give an error:
ciscoasa(config)# dns name-server 4.2.2.2 4.2.2.3
ERROR: DNS must first be enabled.

    Thanks, I know that this little tidbit of information is defined somewhere in the cisco Documents but it’s so nice to be able to find things like this so quickly and easily understood. I don’t spend a great deal of time configuring firewalls and had forgotten this one. You really saved my bacon.,

    Thanks! This was great. Much easier than trying to find it in the Cisco docs. Simple and to the point. Thank you!
