Hello.

I want to say thanks before to you, because I really need your help.

I have the following setup.
I  have internet via cable over a FritzBox and another one via DSL. So 2 Internet sources.

After that I put a TP-Link ER605 as LoadBalancer there. If I connect a Laptop on the first LAN Port of the ER605 I have Internet. And I can Access the network before it.

So it seems I set up everything correct. But now comes the challenge.

I want to connect another Fritzbox as MeshMaster after the LoadBalancer. I set it up as Inter Router. It has a connection to the Internet. If I connect the laptop to the new fritzbox, I have internet too, and I can't access the previews networks. which is good.

Now I set up WireGuard on that FritzBox. But now I have the problem, that the wireguard client, cannot connect to that FritzBox.

I have the feeling, I need to make some settings in the TP-Link ER605, so that the traffic will be forwarded correctly and I don't know what to set up.

I set up a virtual server to link the external and internal port which is used by wireguard.

If I connect a computer before the LoadBalancer and make a telnet command for the IP of the ER605 and the right port, I receive no answer.

I know, I also need to contact the AVM support, but since I want to use the LoadBalancer here, I need that device working too.

Thank you for your help.

If you need further information, please write.

Best Regards.
