-**Large State Tables** - State table entries require about 1 KB of RAM each.
+===== Check State Tables =====
+Navigate to **System -> Advanced -> Firewall & NAT**.
+Check the **Firewall Maximum States** and **Firewall Maximum Table Entries** fields.
+Each State table entry requires about 1 KB of RAM.
   * The default state table size is calculated based on 10% of the available RAM in the firewall.
   * For example, a firewall with 1 GB of RAM will default to 100,000 states which when full would use about 100 MB of RAM.
   * For large environments requiring state tables with several hundred thousand connections, or millions of connections, ensure adequate RAM is available.
