Hi

 

We have an OpenVPN Client-to-Site setup.

I'm able to connect to it, I get an IP from the configured range.

But whenever I do I all lose all connections, I cannot ping to LAN or WAN.

 

We do not use any ACL's.

Yes our Server is ER7206.

The article mentions specifically Android and iOS devices, however we're on Windows.

For testing purposes I've downloaded the OpenVPN onto my Android and there it also doesn't work.

 

Edit: I fixed the issue by downloading an older version of OpenVPN.

which OpenVPN server are you connected to? is it another Omada router? then you must enable split on the OpenVPN server

 

then only traffic is routed to the remote lan

Hi

 

We'd like to use the full tunnel to route all traffic through the company router for security purposes.

We use OpenVPN client on the clients and OpenVPN server on the Omada Cloud OC200 Controller.

We follwed this video: https://www.youtube.com/watch?v=F83QTND3Yp8&ab_channel=TP-LinkGlobalSupport

OC200 is not an OpenVPN server so that may be why it doesn't work. Which router do you have as a server? can you show some screenshots of server config and client config?

 

the configuration between two Omada routers is more or less plug and play.

  @MR.S The router is TP-Link TL-ER7206.

We're not trying to connect 2 Omada routers, we're trying to connect an end user to the LAN.

This exact config has worked in the past.

Ok, so your OpenVPN server is ER7206? 

 

maybe it has something to do with this

The issue is fixed for us. However, maybe TP-Link should look further into this to allow the most recent OpenVPN client versions to work.
