IPTABLES-APPLY(8)               iptables 1.8.4               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.
