IPTABLES-APPLY(8)                         iptables 1.6.0                        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.
