Comodo secure DNS server?

Hello Forum!

I installed Comodo Firewall. During the installation procedure, I can choose an option: I can choose the secure dns server of Comodo, instead of the isp’s dns server.
My question: after the installation, how can I change the dns server? How can I find this option on comodo FW?

Thanks!

You just have to change the TCP/IP Settings of the connection

(Double click connection-Properties-Internet Protocol (TCP/IP)-Properties (In case of XP)

Just change the settings therein to your ISP’s DNS settings and you are done.
