Archer VR2600 LAN to LAN VPN
2016-05-06 16:54:59
Model :

Hardware Version : Not Clear

Firmware Version :

ISP :

I'm trying to connect a remote office to Head Office via a VPN.

The Head Office has a Draytek Vigor 2830 and, until recently, the remote office had a Netgear FVS336 and all worked well. The Netgear box developed a fault so I swapped it over with a spare Draytek 2830 box and, again, all was well.

We have now purchased a T-Link Archer VR2600 and although the IPSec VPN establishes no data will pass along the VPN (although I can ping the devices from the remote office to the Head Office).

I'm no expert in VPN's (they've always just worked!) but I can't figure out why I can ping but can't send or receive data.

Bearing in mind that the Netgear to Draytek and the Draytek to Draytek set ups work I'm assuming that I'm missing some sort of setting on the VR2600.

Has anyone had any experience of this they can share?

Just a quick update should anyone else be having this problem....

TP-Link have replicated the problem so it seems to be a problem with the firmware. I've had to return the router to Amazon for a refund whilst I still could so I won't be able to post a solution.
