Dear,

 

I would like to use Opendns as a DNS in Fortigate 60F firewall. I am using PPPoE and the dns obtained from the ISP.  I would like to edit and use Opendns. I checked DNS option under the network and it is not been used when I check Ipconfig/all in client system. Kindly help. Thank you

Hello

Simply configure your DHCP server to give your clients OpenDNS IP as DNS server.

If you also need to deny clients from using other DNS servers, add a firewall rule to deny DNS traffic towards any destination other then OpenDNS.
