The Security Tab - Firewall
Use this screen to configure the firewall and VPN pass through settings.
Firewall
Firewall Protection. Enable this feature to employ Stateful Packet Inspection (SPI) for more detailed review of
data packets entering your network environment.
Block WAN Request
Block WAN Ping. Enable the Block WAN Ping feature by checking the box beside Block WAN Ping and you can
prevent your network from being “pinged,” or detected, by other Internet users. The Block WAN Ping feature also
reinforces your network security by hiding your network ports. Both functions of the Block WAN Ping feature
make it more difficult for outside users to work their way into your network. This feature is enabled by default.
VPN Pass Through
These settings allow VPN tunnels using PPTP, IPSec, or L2TP protocols to pass through the Router’s firewall.
PPTP Pass through. Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be
tunneled through an IP network. To allow PPTP tunnels to pass through the Router, click Enable.
IPSec Pass through. Internet Protocol Security (IPSec) is a suite of protocols used to implement secure
exchange of packets at the IP layer. To allow IPSec tunnels to pass through the Router, click Enable.
L2TP Pass through. Layer 2 Tunneling Protocol (L2TP) is the method used to enable Point-to-Point sessions via
the Internet on the Layer 2 level. To allow L2TP tunnels to pass through the Router, click Enable.
