L2TP VPN setup on USG60 via Wizard

peterpoon

Dear Sir,

I followed the Quick Setup (via Wizard) instruction of this link: https://community.zyxel.com/en/discussion/4532/how-to-setup-l2tp-vpn

Windows PC client end with relevant IPSec services up and running, encountered error 789 when connecting to L2TP channel.

Any advice from the support for me?

L2TP error 789 is: Security layer encountered error.

You can try to check IKE and AuthIP IPSec keying modules is enabled on your PC. You can restart it and and check if any help.

Sir, both were started and running. See attached screen shot (Word Doc).

Hi, Stanley. Just sent out the document via the MAIL icon (I believed it was the top right hand corner, envelope icon).

Stanley, enabled a Policy Rule for TrustedIP as advised this morning.  Appreciate your taking a peek at our USG60 configuration.

Hi @peterpoon
The issue is come from default policy control rules are deactivated.

From WAN to ZyWALL, Service: IKE/ESP/AH/NATT. Action: allow.
From IPSec to ZyWALL, Service: any, Action: allow.
From IPsec to any. Service: any. Action: allow.

These rules are for VPN connection. After enabling them, L2TP VPN tunnel is working.
