Model: Deco XE75  
Hardware Version: V1
Firmware Version: 1.2.6

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.

Hi, welcome to the community.

Please change the Deco WAN DNS to 8.8.8.8/8.8.4.4 per link:

And is the Synology NAS also connected to Deco?

As for Archer AX21, do you mean only the PPTP VPN client works, OpenVPN and L2TP/IPSec did not work either?

Wait for your reply.

Best regards.

  @David-TP Thanks for replying to me.

 

I followed the instruction from https://www.tp-link.com/us/support/faq/1855/ to manual assign primary/secondary dns, but the result remain the same. The device that I put into the Access list is still unable to access internet but can use the Deco App. Are there other tips that I cantry?

 

For the Synology NAS, it is not connect to Deco and is located in another location. 

For the AX21, I have only tried PPTP and L2tp/IPSec, and yes only PPTP is working. L2TP/IPSec stuck in "Conntecting"

 

Thank you.

Hello @MMBB, I got a firmware update fixed the issue for PPTP, but L2TP/IPSec is still not working on my end.
