I have built a test bench with FreeBSD box as pptp-server based on mpd5 daemon and TL-R605 as pptp-client.
Everything works fine but, when I stops mpd5 daemon on FreeBSD it sends a command to destroy pptp connection
to TL-R605 and then after receiving such command router's pptp-client dies and it doesn't try to reconnect back to pptp-server anymore.
Only router rebooting can restore pptp-session, but if it installed somewhere in the far away it'll get hard to reboot it.
I guess it's not a right behavior for automated systems.
In any case pptp-client on TL-R605 should keep trying to reconnect to pptp-server until pptp-client will be disabled in router's configuration.
Is it possible to change a firmware of TL-R605 to fix this important function.
HW ver: TL-R605 v1.0; FW ver: 1.1.0 Build 20210531 Rel.59047
