12.17 Telecommuter VPN/IPSec Examples

The following examples show how multiple telecommuters can make VPN connections to a
single Prestige at headquarters from remote IPSec routers that use dynamic WAN IP
addresses.

12.17.1 Telecommuters Sharing One VPN Rule Example

Multiple telecommuters can use one VPN rule to simultaneously access a Prestige at
headquarters. They must all use the same IPSec parameters (including the pre-shared key) but
the local IP addresses (or ranges of addresses) cannot overlap. See the following table and
figure for an example.
Having everyone use the same pre-shared key may create a vulnerability. If the pre-shared key
is compromised, all of the VPN connections using that VPN rule are at risk. A recommended
alternative is to use a different VPN rule for each telecommuter and identify them by unique
IDs (see Section 12.17.2 on page

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