In **Firewall Advanced**:

  * Firewall Maximum Table Entries:  **2000000**.

<WRAP info>
**NOTE:**  This value defines the maximum number of entries that can exist inside of address tables used by the firewall.

These entries include blocked addresses, bogons, aliases, ssh/GUI lockout records, hosts blocked by Suricata / Snort alerts, and so on.

By default this is 200,000 entries; which is usually way too low.
