2026.08 - HA on Synology VM - IPv6 trusted proxy configuration

Configuration
1

Good morning,

Ha is installed as a virtual machine on a Synology NAS under DSM 7.4

I use the reverse proxy of the NAS with a name of the form ha..MyDS.me:443 for remote access. This name is dorwarded to ipv4locale:8123.

I now have a trusted proxy in my configuration.yaml file of the form ipv4_du_nas.

When moving to 2026.8, in the new network configuration, this trusted proxy was translated into ipv4_du_nas/32. Why?

Subsidiary question: I would also like to allow IPv6 access: my DDNS supports it, but how should I set this up at the HA level?

This is the CIDR ‘slash’ notation equivalent of

Ipaddr : xxx xxx.xxx xxx
Subnet mask : 255.255.255.255

Which means only that single ip address.

Which means it translated it correctly.

Thank’s !

Another question.
On the menu, Remote access appears as disabled while it is working.

How is the appearance of this message determined? Did I omit something in my configuration?

I answer myself.

It seems that this message appears when the external URL is not filled in. The URL indicated in the Companion App is not taken into account in the display of this warning message
