Remote Management & L2TP VPN

[Orangebloc]

Hi,
Have discovered this project recently. Great work!

I am looking to deploy a couple of routers on remote sites and ideally manage remotely. is it possible to add a L2TP/IPSec VPN connection? I have been looking around the gui and can see Wireguard and OpenVPN but no others?

I am connecting to as Mikrotik endpoint which doesn't have Wireguard (v6) - OpenVPN is not playing ball as I have to add a passphrase when I export the keys and OpenMPTC doesn't seem to accept a passphrase entry anywhere on the config. I may have missed this if I have please let me know?

Thanks
