IPTABLES-APPLY(8)                                            iptables 1.8.2                                            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.

iptables-apply 1.1 -- a safer way to update iptables remotely

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

The script 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
  Specify the timeout in seconds (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 this help text.
-V, --version
  Display version information.
