A VPN is a secure, private connection between two end points. An end point could be a VPN
gateway like the ZyWALL/USG itself or a computer with VPN software installed. Select a VPN wizard
type and click Launch to begin that wizard and end the Initial Setup Wizard with changes saved.
Click Exit to leave the wizard with changes unsaved.
• Select IPSec VPN Settings to create a secure, private connection between two ZyWALL/USGs.
Two networks (sites) behind the ZyWALL/USGs can then communicate securely with each other.
Make sure that the settings on both ZyWALL/USGs are correct and reciprocal. What is a local
setting for one should be the equivalent remote setting on the other. Make sure the pre-shared
key, negotiation mode, encryption, authentication settings, DH key group and so on are the same
on both ZyWALL/USGs.
Make sure that both ZyWALL/USGs are able to communicate with each other. Try pinging one
gateway from a computer behind the other.
Make sure that there is not a firewall blocking VPN traffic in front of one of the ZyWALL/USGs.
• Select IPSec VPN Settings for Configuration Provisioning to create a secure, private
connection between a ZyWALL/USG and a computer with Zyxel client VPN software installed. See
the client VPN software's help to see how to configure it. The computer with client VPN software
installed and the ZyWALL/USG can then communicate securely with each other.
Make sure the client VPN software is installed and configured correctly on the computer. See the
client VPN software's help if anything is unclear.
Make sure the VPN settings such as the pre-shared key (or certificate), negotiation mode,
encryption, authentication settings, DH key groupon the computer and the ZyWALL/USG are
correct. Make sure that the client is able to communicate with the ZyWALL/USG. Try pinging the
ZyWALL/USG from the client.
