Model: ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.2.1

I have a Client-to-Site VPN set up with OpenVPN Server.

 

When connecting to the server via Tunnelblick, a MacOS OpenVPN client, I'm presented with the message:

 

This VPN works now, but may not work in a future version of Tunnelblick.
The OpenVPN configuration file for VPN should be updated so it can be used with modern versions of OpenVPN. It contains these OpenVPN options:
• 'comp-lzo' was deprecated in OpenVPN 2.4 and has been or may be removed in a later version

Tunnelblick will use OpenVPN 2.5.4 - OpenSSL v1.1.1l to connect this configuration.
However, you will not be able to connect to this VPN with future versions of Tunnelblick that do not include a version of OpenVPN that accepts the options

 

Is there anything I can do through the Omada gateway to address this? Or is this something that TP-Link would need to address in a firmware update?

It may be that the OpenVPN version is too low and it will report an error as insecure.
You can try to manually change "comp-lzo adaptive" to "compress lzo" in the exported OVPN file.

 

But I don't think it will affect the actual use of the VPN, although it will give you a similar error.

Just striving to develop myself while helping others.
