How to create a script that disables a specific port forwarding?

[LeandroCorrea]

I need to create a script that disables port forwarding at a specific time. i know it is possible to use crontab to schedule the execution of tasks and scripts, i just don't know how to create the script that disables to a specific port forwarding

I added the time options in the extra arguments field and it seems to work.

root@magiatiko /tmp > iptables-save | grep time
-A zone_wan_prerouting -p tcp -m tcp --dport 5656 -m time --timestart 08:00:00 --timestop 10:00:00 --weekdays Mon --datestop 2038-01-19T03:14:07 -m comment --comment "!fw3: time" -j DNAT --to-destination 10.0.2.3:5656

config redirect
	list proto 'tcp'
	option src_dport '5656'
	option extra '-m time --timestart 08:00:00 --timestop 10:00:00 --weekdays Mon'
	option dest_ip '10.0.2.3'
	option reflection '0'
	option src 'wan'
	option name 'time'
	option dest 'lan'
	option target 'DNAT'

I can't block port 3141 with traffic rule - #17 by vgaetera

Hi @vgaetera.
I couldn't get the traffic rule to work. As an alternative I thought of creating a scheduled task through crontab that disables and enables a specific port forwarding

You should post the firewall config, so we can identify the cause of the problem:

uci show firewall; iptables-save -c
