NAME

6       iptables-apply - a safer way to update iptables remotely
7

SYNOPSIS

9       iptables-apply   [-hV]   [-t  timeout]  [-w  savefile]  {[rulesfile]|-c
10       [runcmd]}
11

DESCRIPTION

13       iptables-apply will  try  to  apply  a  new  rulesfile  (as  output  by
14       iptables-save,  read by iptables-restore) or run a command to configure
15       iptables and then prompt the user whether the changes are okay. If  the
16       new  iptables  rules  cut the existing connection, the user will not be
17       able to answer affirmatively. In this case, the script  rolls  back  to
18       the previous working iptables rules after the timeout expires.
19
20       Successfully  applied  rules  can also be written to savefile and later
21       used to roll back to this state. This can be used to implement a  store
22       last  good  configuration mechanism when experimenting with an iptables
23       setup  script:  iptables-apply  -w  /etc/network/iptables.up.rules   -c
24       /etc/network/iptables.up.run
25
26       When    called    as    ip6tables-apply,    the    script    will   use
27       ip6tables-save/-restore and IPv6 default values instead. Default  value
28       for rulesfile is '/etc/network/iptables.up.rules'.

OPTIONS

31       -t seconds, --timeout seconds
32              Sets  the  timeout  in  seconds after which the script will roll

34
35       -w savefile, --write savefile
36              Specify the savefile where successfully applied  rules  will  be
37              written    to    (default    if    empty    string   is   given:
38              /etc/network/iptables.up.rules).
39
40       -c runcmd, --command runcmd
41              Run command runcmd to configure iptables instead of  applying  a
