1.2.2.2 ZyWALL with NetScreen VPN Tunneling
This section guides how to setup a VPN connection between the ZyWALL 1050 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.
Static IP address
210.110.7.1
Static IP address
167.35.4.3
The central office gateway ZyWALL 1050’s interface and VPN setting retain the same settings
as in the previous example. If you jumped to this section first, please refer to ‘ZyWALL1050
to ZYWALL70 VPN tunnel setting’ on the page 8.
