Hi to All,
Please, can someone explain the image below.

PPTP and SSTP showing unreachable, then every 2 to 5 seconds appearing same PPTP/SSTP reachable.
And also, why our VOIP suddenly we cannot hear their voice, but they can hear us. Very strange like this. I did not change any configuration since 1-2 months, just doing a daily backup.
I also tried to restore the other day that all are working fine. But did not work.
The problem started maybe already 2 weeks.
Thank you!
