hello I would like to empty the cached thanks to crontab on my router I use this command which works very well

I then use 4 traffic rules in luci for my games only as and when in firewall these rules are filled in Mb I would like to be able to reset them approximately every 4 hours is this possible thank you

I use this for the cache but no idea to restart the traffic rules only the 4 rules

This can be useful for debugging things but in general it's not a good idea. Cache is basically harmless, and will be dropped by the kernel on demand. Forcing it to drop can reduce performance but most routers don't do much filesystem reading anyway.

Are you trying to reset the counters so you can see how much traffic the rules have?

yes dlakelan if I can reset the counter every 4 hours that would be great

in the image we see 0 in DSCP prerouting and postrtouing because my game console is not turned on

I don't know if it's a placebo effect but these rules seem to make my gameplay faster for call of duty

could you just do

/etc/init.d/firewall restart

from cron?
