Problem with L2TP OVER IPSEC USG20

Ric

Hello, I followed this guide https://www.zyxel.it/upload/docs/FAQ_usg_vpn_l2tp_win7.pdf, but I have problems. I can connect to the USG (from the monitor-L2tp_over_IPsec I see my device) but I can not access the internal network. I can not ping and see the network devices. I have tried on different devices, but it does not change anything. I connect, but I can not do anything else. Can you help me? Thank you

Alfonso

Hi @Ric

Welcome to the forum.

Does any device get an ip address when it connects?
Can you provide any kind of further information?
Have you tested from an android device?

Hi @Ric,

 

If you're using ZyWALL USG 20, just use Default_L2TP_VPN_GW and Default_L2TP_VPN_Connection to configure L2TP VPN.

Default_L2TP_VPN_GW

Make sure My Address is correctly configured. Configure your own pre-shared key.

Leave other settings as default settings.

Default_L2TP_VPN_Connection

The local policy is the wan IP of your ZyWALL USG 20.

Leave other settings as default settings.

Create a new user account for L2TP connection.

Create a  pool for L2TP VPN clients.

Note that the pool cannot conflict with any WAN/LAN/DMZ/WLAN even if they are not in use.

After L2TP VPN is correctly configured and established, the L2TP client is able to ping device in LAN (ex: 192.168.1.33).

If you’re using USG20-VPN, just follow the steps in wizard to finish L2TP settings.

Hi @Alfonso,

Each device receives an IP address

I tried with an Android device, both wifi and 4g, 1 PC win10, 1 PC winXP.

I try to do other tests.

Remote devices have different IPs than the internal destination.
