Resetting the state tables will remove all entries from
|
| 75 |
|
|
the corresponding tables. This means that all open connections
|
| 76 |
|
|
will be broken and will have to be re-established. This
|
| 77 |
|
|
may be necessary after making substantial changes to the
|
| 78 |
|
|
firewall and/or NAT rules, especially if there are IP protocol
|
| 79 |
5b237745
|
Scott Ullrich
|
mappings (e.g. for PPTP or IPv6) with open connections.<br>
