AR750 no l2tp with 3.010 firmware

you have removed l2tp with block in case of disconnection from firmware 3.010 of ar750. I need this function, is there any way to put it back on this firmware? NO OVPN, L2TP!

In the latest firmware, we had removed PPTP and L2TP.

If you want to use them, you can refer to OpenWRT’s guide.

inserting this function does not seem user friendly. is there something simpler?

You will have to follow the guide Kyson sent you.
The GL UI is focusing on more advanced VPN protocols like Wireguard which are more secure, faster and future proof.
