NetBIOS Broadcast
Forwarding
Select Enable to send NetBIOS (Network Basic Input/Output System)
packets through the VPN connection. NetBIOS packets 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.
Dead Peer Detection
Select Enable to force the cable modem/router to periodically detect if
the remote IPSec cable modem/router is available or not.
Manual Encryption
Key
If Manual mode is selected in the Key Management field, enter a 16
hexadecimal digits manual encryption key for encryption.
Manual Authentication
Key
Enter a 32 hexadecimal digit unique authentication key to be used by
IPSec.
Inbound SPI Enter a unique SPI (Security Parameter Index) for inbound SPI.
Outbound SPI Enter a unique SPI (Security Parameter Index) for outbound SPI.
L2TP/PPTP
The L2TP/PPTP page allows you to configure server and security settings. The L2TP (Layer 2
Tunneling Protocol) and PPTP (Point-to-Point Tunneling Protocol) both allow PPP frames to be
tunneled through the network. PPTP is a Microsoft proprietary protocol, which is very similar to
L2TP.
To access the L2TP/PPTP page:
1 Click VPN in the menu bar.
2 Then click the L2TP/PPTP submenu.
Figure 43 shows an example of the menu and Table 33 describes the items you can select.
