iptables-apply
iptables-apply(8) System Manager's Manual iptables-apply(8)NAME
iptables-apply - a safer way to update iptables remotely
SYNOPSIS
iptables-apply [-hV] [-t timeout] ruleset-file
DESCRIPTION
iptables-apply will try to apply a new ruleset (as output by iptables-save/read by iptables-restore) to iptables, then prompt the user
whether the changes are okay. If the new ruleset cut the existing connection, the user will not be able to answer affirmatively. In this
case, the script rolls back to the previous ruleset after the timeout expired. The timeout can be set with -t.
When called as ip6tables-apply, the script will use ip6tables-save/-restore instead.
OPTIONS -t seconds, --timeout seconds
Sets the timeout after which the script will roll back to the previous ruleset.
-h, --help
Display usage information.
-V, --version
Display version information.
