ZT DSM 7.2.1 + OPENVPN not working together

[pitiriguisvi]

I have tried the following:

• [ x] Disabling QuickConnect
• [ x] Disabling OpenVPN
• [ x] Restoring web port to default (5000/5001)
• [ x] Restarting NAS
• [ x] Reinstall ZT
• [ x] Checked for presence of dev/net/tun
• [ x] Verified that ZT is or is not running with ps aux | grep zerotier
• confirmed that config files exist in /var/packages/zerotier/target/var
• [x ] Issued zerotier-cli commands as root

I am aware of the following

• [ x] The GUI is deprecated and may not work on my particular NAS
• [x ] The CLI is the recommended interface for controlling ZT

Other important information

• Model: DS3622xs
• Current DSM version: DSM 7.2.1-69057 Update 1
• DSM version when issue was first observed: DSM 7.2.1-69057

¡Hello!
I´ve updated DSM from 6.2.3 to 7.2.1 and installed ZT vía docker as per documentation. The thing is, that when i load ZT docker, i am unable to see any interfaces on VPN SERVER package (inside "global configuration"). When i turn on ZT , openvpn stops working.

On DSM 6.2.3 i was able to see the ZT interfaces inside control panel > network > network interface. Now on DSM 7 i cant (is this normal?).

Also. Do i need to enable open vSwitch?
