Hi,
You can refer to the link below to set up the VPN Server or VPN client feature on the Deco.
How to set up The VPN Server/VPN Client Feature on a Deco Mesh Wi-Fi Router?
 

As you can see in the above link, if you have configured the main Deco as a VPN client, all devices connected to the Deco network can access the remote VPN server if you select All Clients on the Access Permission page, no matter which Deco is the device connected to, and you can also select a specific device connected to the Deco network to access the VPN server.

Best Regards
