Plz Explain "And" / "Or" Firewall Rule


Can someone plz tell me when to use “And” and when to use “Or” when creating firewall rules.

For example, if i create a rule saying if country does not equal USA “And” UK then challenge this works correctly.

But if i say USA “Or” UK, then i get challenged from UK which i shouldn’t.

So i’m very confused when “And” / “Or” should be used!


If you are using more than one country code for the same condition, you’d better use “is not in” instead of “does not equal”. So resulting expression would be:

(not in {"US" "GB"})

which would apply the chosen action to anyone coming from any country except United States and United Kingdom.
