Static ARP entries keep vanishing

[samirchagan]

Hello everyone,

First of all, @RMerlin and everyone involved in this project, you are awesome!!

My first post here. Using Merlin firmware recently and it is delightful!

Upgraded from 3004.388.6 to 3004.388.7 and noticed a strange behavior. Basically static arp entries in the services-start script disappear randomly without any action on my side.

The script loads 3 entries and they show as PERM on the arp list, but at this moment one of the entries is missing. Ran services-start manually and the 3 entries are set in the arp list. I used to reboot every night, but sometimes the entries get lost before the 24 hour mark.

cru l shows this:
*/2 * * * * /etc/openvpn/server1/vpn-watchdog1.sh #CheckVPNServer1#
*/2 * * * * /etc/openvpn/server2/vpn-watchdog2.sh #CheckVPNServer2#

There is an old post in the forum but with no resolution.

PS: Yes, I could add it as a cron job... but would like to understand why this is happening.

Thanks guys!!

EDIT: roughly 3h24m later it happened again.

The same thing happens with my GT-AX6000 since I bought it last month (first firm 388.6_2, did not even tried stock fw, first power on => merlin flash)
I tought the arp flush was kernel related and normal (did not happen on my AC87U). Solved it through cron job.

Cheers

OT: Add a signature with your setup and you won´t have to write it in your posts.

Done also!
Thanks for the tip, I like to name the model on the post itself in case someone reads it in the future and my sig is changed with a newer model.

Cheers!
