IPTABLES-APPLY(8)               iptables 1.8.5               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.
