IPTABLES-APPLY(8)                iptables 1.8.6                IPTABLES-APPLY(8)



NAME
       iptables-apply - a safer way to update iptables remotely

SYNOPSIS
       iptables-apply [-hV] [-t timeout] [-w savefile] {[rulesfile]|-c [runcmd]}

DESCRIPTION
       iptables-apply will try to apply a new rulesfile (as output by iptables-
       save, read by iptables-restore) or run a command to configure iptables
       and then prompt the user whether the changes are okay. If the new
       iptables rules cut the existing connection, the user will not be able to
       answer affirmatively. In this case, the script rolls back to the previous
       working iptables rules after the timeout expires.

       Successfully applied rules can also be written to savefile and later used
       to roll back to this state. This can be used to implement a store last
       good configuration mechanism when experimenting with an iptables setup
       script: iptables-apply -w /etc/network/iptables.up.rules -c
       /etc/network/iptables.up.run

       When called as ip6tables-apply, the script will use
       ip6tables-save/-restore and IPv6 default values instead. Default value
       for rulesfile is '/etc/network/iptables.up.rules'.

OPTIONS
       -t seconds, --timeout seconds
              Sets the timeout in seconds after which the script will roll back
              to the previous ruleset (default: 10).

       -w savefile, --write savefile
              Specify the savefile where successfully applied rules will be
              written to (default if empty string is given:
              /etc/network/iptables.up.rules).

       -c runcmd, --command runcmd
              Run command runcmd to configure iptables instead of applying a
              rulesfile (default: /etc/network/iptables.up.run).

       -h, --help
              Display usage information.

       -V, --version
              Display version information.
