LABEL DESCRIPTION
Windows Networking
(NetBIOS over TCP/IP) NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast
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.

16.17 Telecommuter VPN/IPSec Examples
The following examples show how multiple telecommuters can make VPN connections to a single Prestige at
headquarters. The telecommuters use IPSec routers with dynamic WAN IP addresses. The Prestige at
headquarters has a static public IP address.
16.17.1 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 Prestige 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.
