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.
