6.4.4 VPN - L2TP / PPTP

Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private
networks (VPNs).
PPTP (Point-to-Point Tunneling Protocol) is a Microsoft proprietary protocol (RFC 2637 for
PPTP is informational only) to tunnel PPP frames, which is very similar to L2TP.
DDW2600/DDC2700
setup, but is not so secure. Select DH1, DH2 or DH5 to
enable PFS.
After enable PFS, you need to choose DHx.
As a VPN setup is processing intensive, the system is
vulnerable to Denial of Service (DOS) attacks. The IPSec
receiver can detect and reject old or duplicate packets to
protect against replay attacks. Enable replay detection by
selecting this check box.
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. Select this check box to send
NetBIOS packets through the VPN connection.
Force wireless router to detect if the remote IPSec gateway
is available or not periodically.
