1.2.2.2 ZyWALL with NetScreen VPN Tunneling

This section guides how to setup a VPN connection between the ZyWALL USG 2000 and
NetScreen 5GT.
As on the figure below, the tunnel between Central and Remote offices ensures the packet
flows between them are secure. This is because the packets flowing through the IPSec tunnel
are encrypted. The required settings to setup this VPN tunnel using ZyWALL and NetScreen
are stated in the following section.
Central Office Gateway
ZyWALL
LAN: 192.168.1.X
The central office gateway ZyWALL USG 2000's interface and VPN setting retain the same
settings as in the previous example. If you jumped to this section first, please refer to
'ZyWALL USG 2000 to ZYWALL70 VPN tunnel setting' on the page 8.
