IPTABLES-APPLY(8)                          iptables 1.8.7                          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.
