Chapter 16 VPN Screens The following table describes the fields in this screen. Table 97 VPN: Global Setting LABEL DESCRIPTION Windows Networking NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that (NetBIOS over TCP/IP) 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. Apply Click Apply to save your changes back to the ZyXEL Device. Cancel Click Cancel to begin configuring this screen afresh. 16.18 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. 16.18.1 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.
