IPTABLES-APPLY(8) iptables 1.4.21 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.
