IPTABLES-APPLY(8)                               IPTABLES-APPLY(8)

          iptables-apply - a safer way to update iptables remotely

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

          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

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

          -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:

          -c runcmd, --command runcmd
               Run command runcmd to configure iptables instead of
               applying a rulesfile (default:

          -h, --help
               Display usage information.

          -V, --version
               Display version information.
