Hello Support Team,

I am contacting you regarding my TP-Link Archer MR400 router.

Device details:
— Device version: Archer MR400 v4.3 (00000002)
— Firmware version: 1.4.0 0.9.1 v0001.0 Build 240719 Rel.49247n

I recently purchased this router at a discount and was very happy with my purchase. I planned to use it to connect to my L2TP/IPsec VPN server, however, unfortunately, I could not find such an option in the router settings. I only see L2TP connection without IPsec support.

Could you please let me know if there is any firmware available (including beta or alternative official firmware) for my device that supports L2TP/IPsec? This feature is very important for me, as it was one of the main reasons I chose this router.

I would be extremely grateful for your help and any information you can provide. I truly hope there is a solution that will allow me to fully use my router.

Thank you very much in advance for your support.

Kind regards,
[NotiCute]

You’re not missing anything — on the Archer MR400 V4, TP-Link has indeed removed native IPSec client support. For this hardware/firmware generation, the router only supports OpenVPN and PPTP, and unfortunately IPSec isn’t hidden or disabled; it’s simply not implemented.

As far as the community knows, there’s no official beta or firmware patch that adds IPSec to V4. Downgrading firmware also won’t help, since IPSec was never included for this hardware revision.

If IPSec is a hard requirement, your realistic options are:

• Use OpenVPN instead (if your home network supports it)

• Run an IPSec/OpenVPN client on a device behind the router (PC, Raspberry Pi, firewall)

• Replace the router with a model that explicitly lists IPSec VPN client support

You’re right that TP-Link’s product pages can be confusing here — VPN “support” doesn’t always mean IPSec anymore, especially on LTE models.
