Firewall - A firewall protects your network from the outside world. In this page, the user can
enable or disable the router firewall.
VPN - VPN Passthrough must be enabled if you want to allow VPN tunnels using VPN proto-
cols to pass through the device.
SPI Firewall - Stateful Packet Inspection (SPI) helps to prevent cyber attacks by tracking
more state per session. It validates that the traffic passing through the session conforms
to the protocol. SPI Firewall is enabled by factory default. If you want all the computers on
the LAN exposed to the outside world, you can disable this option.
PPTP Passthrough - Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Pro-
tocol (PPP) to be tunneled through an IP network. To allow PPTP tunnels to pass through
the device, click on Enabled.
L2TP Passthrough - Layer Two Tunneling Protocol (L2TP) is the method used to enable
Point-to-Point sessions via the Internet on the Layer Two level. To allow L2TP tunnels to
pass through the device, click on Enable.
IPSec Passthrough - Internet Protocol security (IPSec) is a suite of protocols for ensuring
private, secure communications over Internet Protocol (IP) networks, through the use of
cryptographic security services. To allow IPSec tunnels to pass through the device, click on
Enable.
