Firewall state table

Resetting the state tables will remove all entries from the corresponding tables. This means that all open connections will be broken and will have to be re-established. This may be necessary after making substantial changes to the firewall and/or NAT rules, especially if there are IP protocol mappings (e.g. for PPTP or IPv6) with open connections.

The firewall will normally leave the state tables intact when changing rules.

NOTE: If you reset the firewall state table, the browser session may appear to be hung after clicking "Reset". Simply refresh the page to continue.
