You don't. You hand the DNS server out directly to your clients in the DHCP pool for your clients

Re: DNS on ASA 5520

Hi Rabih,

You don't need to configure DNS server on the ASA to browse the internet. If you would like to ping websites with names and do a few other things with DNS on the ASA, then you need to add the DNS server on the ASA configuration.

dns domain-lookup " interface name "

dns name-server " ip address of dns server"

If you want to push the dns server settings to your internal clients, you need to add that to the dhcpd settings on the Cisco ASA,

dhcpd dns " server ip address "

Please find below, the guide to setting up the ASA as a DHCP server,

Let me know if that helps.


Cheers,

Nash
