In Winbox or CLI does ! tickbox mean NOT EQUAL TO <> ?

RouterOS General

Hi All,

I am looking at using a firewall filter rule that drops if destination address <> DOES NOT EQUAL a network.

My grey matter vaguely recalls the ! tickbox when ticked means just this.

For example it might be something like:

add action=drop chain=input dst-address=!192.168.45.0/24

Can you help please.

Regards

Aidan

Correct, the ! tickbox is negation (NOT).

Correct, in your example it means drop all traffic that wants to hit the router if it is not destined for 192.168.45.0/24

Please note that this rule will only block traffic to the router. Not traffic going through the router.
