Yesterday I bought new vpn service and perfect work all devices. I have tried change vpn policy and selected 2 mac addresses with no vpn. Homeassistant can detect WAN and VPN IP addreses and problem with duckdns which saying log with WAN IP address then changed to VPN IP address.
My router is Flint 2 and frimware version is 4.5.6.
I feel that policy does not work perfect? 2nd device is proxmox which working with homeassistant.
Hmm, how is hassio connected?
I see it does not reference a mac address and marks it with a ? meaning the device looks offline.
i think it would be usefull to show the topology here, is it wired or connected to a switch or is it wireless?
It looks to me something disconnect the port frequently but this can sometimes also occur on a switch.

Proxmox has real mac address and static IP addres 192.168.20.2
Hasio has made virtual mac address and static IP address 192.168.20.3
Without vpn is working perfect 
. I saw logs in duckdns and why conflict between wan and vpn addresses
Try to traceroute the 'duckdns', to see how it goes
I don't know how to traceroute. In the console only CLI
After a few days, Hasio worked as normal with WAN, not VPN. no more notifications from my telegram. Probably is duckdns server problems.
I have tried proxmox shell with command traceroute
