@Svamitva_IT those screenshots didn't say much, i was wondering what you are missing when configuring the vpn on the omada controller. you have to press advanced in vpn config for more options.

@EffiTrax Ok, so your OpenVPN server is ER7206? maybe it has something to do with this https://community.tp-link.com/en/business/forum/topic/653224

@EffiTrax 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...

@EffiTrax 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

@Svamitva_IT what are you missing from vpn configuration in controller mode that you have in stand alone? some screenshots would have helped a bit
