Check that a policy is working
Once you have created a policy to block a domain, you can use either dig
or nslookup
on your to see if the policy is working as intended.
If you are using a policy to block example.com
, you can do the following to see if Gateway is blocking example.com
:
-
Open your terminal.
-
Type
dig example.com
(nslookup example.com
) if you are using Windows) and press enter. -
If the Block page is disabled for the policy, then you should see
REFUSED
in the answer section:
If the Block page is enabled for the policy, then you should see NOERROR
in the answer section and 162.159.36.12
and 162.159.46.12
as the answers when the domain is successfully blocked.
Test a DNS policy
If you are blocking a security threat or content category, you can test that the policy is working by using the test domain associated with each category.
Once you have configured your Gateway policy to block the category, the test domain will show a block page when you attempt to visit the domain in your browser, or will return REFUSED
when you perform dig
using the command-line interface.
