Hello everyone,

I'm seeking assistance with troubleshooting a recent firmware update that enabled the VPN client on my Deco device. Here's an overview of the issue:

I have a VPN server running on a Synology NAS, and I can successfully access the different VPN configurations (PPTP or L2TP/IPSec) from my iPhone, Mac, or Windows devices without any problems. However, when attempting to set up the connection on my Deco device, I encountered the following results:

1. PPTP: Deco is able to establish a connection.
2. OpenVPN: Deco is able to establish a connection.
3. L2TP/IPSec: Deco shows "Connecting" but is unable to set up a connection.

Even when the connection is successfully established, any device added to the "Access Permission" -> "Client List" on the Deco device is unable to access the internet.

Prior to switching to Deco, I had an AX21 router with a built-in VPN client. With that router, I was able to use PPTP VPN and selectively allow certain devices to utilize the VPN connection without encountering any issues. (L2TP/IPSec also not working)

I would appreciate guidance on further troubleshooting steps. Thank you.
