Setup L2TP VPN on CentOS/Ubuntu without Pre-shared Key
Hello,
Can anyone give me a guide from somewhere on how to setup L2TP without requiring clients for a pre-shared key? There are many install scripts available online and it works but it requires clients to have a pre-shared key. Unfortunately, my ISP gave me a locked router than can only connect to L2TP with username and password. I hope someone here can help me.

Just google something like "setup l2tp without ipsec"
Uh, you can literally use the exact same scripts that people use for L2TP/IPSec setups. Just enter any random IPSec Pre-Shared Secret and when it comes time to use it, just skip over the part where a IPSec PSK is required.
Just also make sure that UDP port 1701 isn't filtered and you're good to go.
If I can remember correctly, xl2tpd allows any machine to establish a L2TP connection without establishing an IPSec Security Association.

Thanks guys. Will go with the L2TP without IPSec.
An update. I set it up correctly with SoftEther on Windows Server 2016 using SecureNAT.
Another problem I have is that my ISP only has IPv4, any chance I can get IPv6 to work on my internet connection using SoftEther's SecureNAT?
You should be able to create an ipv6 router on Windows server by enabling the rras feature and assigning it an ipv6 subnet supplied by your provider.
I did but could not get IPv6 internet to work on the client-side... Anyone here have a good guide for client without IPv6 to connect to IPv6 over IPv4 remotely?
Nevermind, I managed to do it on Ubuntu using OpenVPN. Finally figured it out after so long.
Yup when in doubt go with open source solutions with solid documentation
