Chapter 16 VPN Screens

The following table describes the fields in this screen.

The following examples show how multiple telecommuters can make VPN connections to a 
single ZyXEL Device at headquarters. The telecommuters use IPSec routers with dynamic 
WAN IP addresses. The ZyXEL Device at headquarters has a static public IP address.

See the following figure and table for an example configuration that allows multiple 
telecommuters (A, B and C in the figure) to use one VPN rule to simultaneously access a 
ZyXEL Device at headquarters (HQ in the figure). The telecommuters do not have domain 
names mapped to the WAN IP addresses of their IPSec routers. The telecommuters must all 
use the same IPSec parameters but the local IP addresses (or ranges of addresses) should not 
overlap.

Windows Networking 

(NetBIOS over TCP/IP)

NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that 

enable a computer to find other computers. It may sometimes be necessary to 

allow NetBIOS packets to pass through VPN tunnels in order to allow local 

computers to find computers on the remote network and vice versa.

Allow NetBIOS Traffic 

Through All IPSec 

Tunnels

Select this check box to send NetBIOS packets through the VPN connection.
