Firewall is a function for blocking unwanted traffic at the account level. This blocking is valid for all campaigns of the account and for all users of the account.
Operation logic
If the blocking rule matches, the user who made the visit will be shown a 500 error, i.e. the user will not go through the campaign funnel. There will also be no statistics for this visit.
The AND operation is applied inside the firewall rule, i.e. all conditions specified in the rule are met.
The OR operation is applied between firewall rules, i.e. until the first match.
Creating blocking rules
To block unwanted traffic:
1. Go to Settings.
2. Go to the Firewall section.
3. Enable blocking.
4. Create a blocking rule. The format for entering blocking rules corresponds to the format for setting up redirection rules.
5. Save the changes.
The limit is 50 blocking rules.
