Hi,
I have an operational IKEv2 VPN implemented with Strongswan.

The VPN works well, however with the newly purchased TL-MR6400 clients can establish a VPN but traffic doesn't seem to route through.

I have tested the following combinations:


1. Sim card A, TL-MR6040, IPSec Passthrough - Enabled - No traffic
2. Sim card A, huawei mifi - Works
3. Sim card A, TL-MR6040, IPSec Passthrough - Enabled - No traffic
4. Sim card B, huawei mifi - Works
5. Sim card A, TL-MR6040, IPSec Passthrough - Disabled - No connection at all

In scenario 1. above I am able to ping the VPN's public gateway address but nothing else.

The network of Sim card A is Vodafone (Australia).

The network address reported in TL-MR6400 status page is something like 10.16.91.42.
The network address reported in the VPN server (of the client, ie TL-MR6400) is 120.19.91.91 (Hasn't changed in 3 reconnects).

Firmware version is 1.012 Build 160322 Rel.33912n
Hardware version is MR6400 v1 00000000

Let me know if I can specify any further details.

Thanks.

Hi,

I've the same symptoms. IKEv2 VPN connects but no
passthrough(expect ping).
Settings at "Security" >> "Basic Security" have no effect on data traffic in tunnel.

This problem seems to be very similar to the MR200:

It will be great from TP-Link that the little brother of the MR200: the MR6400 could also get a beta firmware correcting this bug.


Regards.

Hello,

Good news: it also exists a beta (old) firmware for the TL-MR6400. I recently got a link from TP-Link support.
This beta firmware upgrade (beta
2016-09-06 15.01.35 ) solved my VPN (IKEv1/IKEv2) passthrough problems.

My advice is to continue requesting support from TP-Link using their website (http://www.tp-link.com/support-contact.html#E-mail-Support ), you might also be lucky .


CU.

Exact same problem here. I have a Cisco 877 router connected to port LAN1 on the MR6400, it initiates a site to site VPN to another Cisco router across the internet with traffic passing through the MR6400.

However, this will only work when using the MR6400 as a "Standard Wireless Router" with a wired connection to the internet in port LAN4/WAN. When operating as a "3G/4G Router" the VPN tunnel is created but no traffic is able to pass through it.

I have raised a support query to see if a fix or the beta firmware are available
