1. Login to the router
2. Click on 'VPN >> VPN Account'
3. Add a name for your reference
4. Enter a username/password this will be used for authentication
5. Make sure the 'Tunnel' is enabled and 'Connection Type' is set to 'Remote Accecss'
6. Click on 'Add'
7. Click on 'IPSec'
8. Click on 'Add'
9. Enable 'L2TP over IPSec'
10. Enter a Connection Name for your reference
11. Tick the 'Anonymous' option for 'Remote Security Gateway'
12. Enter a 'Pre-Shared Key' this will be used for the tunnel
13. Click on 'Apply'
14. You will be reverted back to the 'IPSec' page
15. Enable 'NAT Traversal' and click on 'Apply'
16. Click on 'L2TP >> L2TP Server'
17. Enable 'L2TP'
18. WAN Interface should be 'Default or IPSec Tunnel'
19. Auth.Type = Chap
20. IP Addresses Assigned to Peer = a IP address outside the DHCP range eg 192.168.1.200
21. Click on 'Apply'

Windows machine can connect fine using this:

android setting are as follows.

I imagine it might be to do with the authentication type, but there appears to be no way to amend this (this is an Android One phone, so stock Android). Can you see anything in the above screenshot that is incorrect wrt the android settings?

I didn't quite follow your question above - were you suggesting setting up the router differently with just a VPN - whilst I'm sure this would work, it defeats the more secure solution I have set up at present.

Thanks!

Unlike L2TP, this works, but if it gives any clues to problem solving:
A) The only encryption available from Android 9.0 is "PPP encryption (MPPE)"
B) This requires Auth type (in PPTP section of router settings) to be set to "MS-CHAPv2"

It doesn't go anywhere toward getting L2TP running though!

I don't know if it is of any relevance, but the only authentication (in L2TP section of router settings) are pap or chap.
