VPN with AT&T BGW320-500

VPN
1

I’m trying to set up a VPN on the TL-R605. I’ve setup openvpn and L2TP but I am unable to connect to either.

My suspicion is that the AT&T ONT/Router is causing issues for me as it has been for lots of others.

Question, has anyone been successful getting VPN to work with the BGW320-500 → TL-R605 setup? If so, what is your configuration?

The AT&T hardware should be in passthrough mode, but maybe I’m missing something?

Two of the best guides I’ve followed have been: Mactelcom’s walkthrough: https://www.youtube.com/watch?v=1ABSqPYTG4c and this setup guide for passthrough on the AT&T https://imgur.com/gallery/1T0vlJH

Thanks.

SOLVED: I entered the wrong MAC Address in the AT&T passthrough screen

Weird, I followed the instructions in the link above and I was able to get the VPN to work with my BGW320-500->TL-R605 running IP Passthru. What is the error you’re receiving?

As a follow-up, even some guidance on finding log events could help track this down. If I find anything I will share.

Question, you’re running from out of the network correct?

​

When I try Open VPN (with the .ovpn file updated to my DDNS domain) nothing happens.

When I try to make an L2TP connection I see the following:

VPN Connection

The L@TP-VPN server did not respond.
Try reconnecting. If the problem continues, verify your settings and contact your Administrator.

Correct, I have to hop on cell to VPN in. I did try from my guest network but I don’t think TP-Link allows for hairpin routing (could be wrong on that though).

Ok, you helped me track it down, many thanks!!

Turns out I entered the MAC address for the router from the controller page and it was different from the one in the AT&T router by one byte (the last two hex values).

So close that I missed it. Now that the MAC address is correct it connects just fine.

This is for L2TP and for Open VPN.
