Resetting the state tables will remove all entries from
|
|
83
|
the corresponding tables. This means that all open connections
|
|
84
|
will be broken and will have to be re-established. This
|
|
85
|
may be necessary after making substantial changes to the
|
|
86
|
firewall and/or NAT rules, especially if there are IP protocol
|
|
87
|
mappings (e.g. for PPTP or IPv6) with open connections.<br>

NOTE: If you reset the firewall state table, the browser
