Tenda W15E Router IPSec, PPTP or L2TP Router to Client VPN connection

[billsecond]

I am trying to connect a Tenda router to my network via Router to Client configuration using L2TP, but here is my problem. I am not seeing a secrete key field in the Tenda, any ideas?

L2TP doesn't require a 'key'. There is an optional 'secret' but you don't need to enter that in pfSense.

But do you really need L2TP? It looks like it support IPSec, can you not use that?
