Hello


have USG20W-VPN and try to make L2TP connection from android.

I use Easy VPN Mode, router to configure.

I've a first IPSec configured, this use SSL and not L2TP

When I try to connect my android phone, the connexion seems negotiate between first IPSec configuration and never with second configuration...


How I can tell to use second L2TP Ipsec configuration when android phone L2TP connection coming?

Thank you for any help,

Regards

    Hi @fleb

    If there are multiple IPSec VPN Connection settings, you can Go to Configuration > VPN > L2TP VPN to choose the preferred VPN connection rule in L2TP setting page.

    To build L2TP VPN connection on the android phone, you may refer to the guideline as below:
