Where is the "Nail-UP" or "Keep Alive" or "Dead Peer Detection" ?

I cannot maintain a VPN connection. The VPN connects once, then fails after a minute or two, then never reconnects back unless I manually uncheck, save, recheck the connection to force initial connect.  Need it nailed up!

I tried with, and without the 1-1 nat policy applied.  Same results.

DPD is enable by default in Nebula. so you cannot see the options in Nebula.

Into VPN connection.

Hi @Rix,
DPD is in phase 1 VPN gateway.
Nailed-up is in phase 2 VPN connection.

But the IPSecVPN does not work with Nebula.  Evidently the Nail-Up option is missing. I removed from Nebula and factory-defaulted to on-premise mode and had it set up and working in under 30 minutes.  I spent close to 20 hours tinkering with Nebula with no success. In my humble opnion, Nebula is not ready for prime time until the missing controls can be overcome with SSH or Local access to fill in the missing features. Another negative experience is trying to work with the LOG.  Search doesn't refresh, it has to be refreshed manually and each time it takes 15-20 seconds, only to have to refresh again in every few minutes.  On premise logs are instant. I won't consider Nebula for firewalls for at least another year. Its okay to manage AP's, but that's about it.

Dear Zyxel team, could you update the Dead Peer Detection (DPD) feature in the Nebula cloud, I need this feature, thanks.
