Creating White list for DNS Tunnel Detection

You can create white lists for IP address you consider safe. If a detected DNS tunnel IP address matches an address in the white list, DNS tunnel detection is bypassed.

To create a DNS white list

1. Navigate to POLICY | DNS Security > Settings.
2. Hover over to the DNS Tunnel Detection tab.
3. Click on the White List for DNS Tunnel Detection tab.

4. For each IP address you want to add to the white list:

   1. Click +Add. The Add One White Entry dialog displays.
   2. In the IP Address field, enter the IP address of the domain to be added to the whitelist.
   3. Click Save.
