IPTABLES-APPLY(8)				       iptables 1.8.11					   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 com‐
       mand  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:  ipta‐
       bles-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/ipta‐
	      bles.up.run).

       -h, --help
	      Display usage information.

       -V, --version
	      Display version information.
