The following table describes the fields in this screen.
13.18 Telecommuter VPN/IPSec Examples
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.
13.18.1 Telecommuters Sharing One VPN Rule Example
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.

LABEL DESCRIPTION
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.

Through All IPSec
Tunnels
Select this check box to send NetBIOS packets through the VPN connection.
