Hi @Vincent-TP,

Thanks for helping me.

I did like this:

First, I made a new VLAN (Number is 42). The IP-Address is 192.168.42.x

No ethernet ports are specified for this VLAN.

Then I made a new VPN Connection:

The local network is the just created "L2TP_VPN" (IP-Addresses 192.168.42.x). The Default network is the one with the IP-Addresses 192.168.0.x. The ER8411 (Router) is 192.168.0.12. The ER8411 is connected to the Internet with WAN-port No 4.

Both DNS Server are from the ISP.

This is the default VLAN:

And there is one other VLAN called "Voice VLAN":

But I don't know where it comes from. Maybe a friend has created it in former times.

I don't know what it is necessary for. If you think it can course problems, I will delete it??

And then there is the Port forwarding:

I had the three ports for L2TP active because in former times I had the Synology Rackstation running as a VPN-Server. But by now it is stopped.

And I had a static route.

But if I understand correctly this can be disabled?

Thanks for helping me,

Regards.

By now I tried different things.

And I Think this works:

First, I deleted the "VOICE LAN". I read a post in this community, and I think it was like it is written. It was only for the phone. But I only have one WLAN-phone and this works fine without the "VOICE LAN".

Then I changed the V-LAN Setting like shown in the screenshot:

The VPN-settings are shown in the next screenshot:

And then I had to do a routing like this:

After connecting as "gu..." to the VPN the routing table looks like this:

And this seems to work properly.

But I think it's to complicated.

There must be a more easy way??

Would you please help me to find an easier way?

Thanks in advance.

GuWen

Hello all,
It seems I got my hopes up a little too soon.
After everything seemed to be working yesterday, today I once again have no access to some websites (e.g., harley-davidson-dot-com).
What also surprised me yesterday was that I was taken directly to the English (US) website instead of the German Harley-Davidson website. However, the OC300 and ER8411 are located in Germany and also have an IP address with a German location.
Therefore, I still need your help in resolving this issue.

Thank you.
