Do you have a tutorial video on how to configure L2TP in OpenWRT? And also a tutorial video for L2TP with IPsec.
why do u need a video all the settings can be find in text form
https://openwrt.org/docs/guide-user/services/vpn/libreswan/openswanxl2tpvpn
but i never tryed to set up l2tp
why do u need l2tp maybe wireguard is better?
I have the same need , I have a Unifi UDM Pro router that act as L2TP / IPSEC VPN SERVER.
