ASA PPPoE Connection and Public DNS servers

[i716]

I have replaced an old Juniper NetScreen device with an ASA. The ASA is connected to an ADSL modem and gets its IP via PPPoE. There are no issues with that. Unfortunately, it uses the ISP's DNS servers by default. On the old NetScreen device, I was able to use public DNS servers, e.g. 1.1.1.1 or 8.8.8.8.

This did however require a command to make it permanent, because otherwise it would revert back to the ISP's DNS server after a reboot. That command was set PPPoE DHCP-nochange I think.

Is there a way to achieve the same on the ASA?

You can configure DHCP on your ASA to use the DNS, WINS, and Domain name it obtains from the outside interface using DHCP or PPPOE by using the dhcpd auto_config command.

For example, your outside interface is setup for PPPOE. Use the following for your ASA to hand out dhcp addresses in the 1.1.1.1 or 8.8.8.8. and the DNS, WINS, and domain name that it receives from the ISP.
