ZyWall USG20 - Old - VPN Setup

MatteoBasso

Hello everybody

I Have a ZyWall with Firmware 3.30(BDQ.5) 15/05/2014.

I Can't set-up VPN via L2TP. All the guides I have read or watched on Youtube has different method, maybe because the firmware is newer and little bit different. 
Anyway, trying some solutions I can't connect. 

Has Anyone a guide that could help me? 
The Wizard doesn't have the L2TP option but only 

VPN Settings

• The later steps will guide you to setup the VPN.
• - Wizard Type
• - VPN Settings
• - Wizard Completed

VPN Settings for Configuration Provisioning

• The later steps will guide you to setup the VPN.
• - Wizard Type
• - VPN Settings
• - Wizard Completed

And I can't find L2TP as many tutorial has.

Please help me. 

Thank you

Go to L2TP> Select VPN connection rule, IP pool for l2tp client and allow user


Note: If established l2tp tunnel with Iphone, please select the related algorithm.

Thank you for the reply. I have tried to do as suggested but doesn't work. 
Let me show you....

1) VPN Connection 

WIZ_VPN

I have created ad object named WAN as you told me, putting the firewall's public IP adress , than I have added the various Encryption proposals





So on VPN Gateway section I just putted the Pre-Shared Key and the Encryption list like the one before. 




Finally on L2TP Section I Have created a "test" user with a password, an IP address pool.
 


Unfortunately it doesn't work. I don't know If I have to set something on Firewall rules.

Please help me,

thank you,
