Chapter 4 Configure the Router in Wireless Router Mode • Firewall - A firewall protects your network from internet attacks. • Enable SPI Firewall - SPI (Stateful Packet Inspection, also known as dynamic packet filtering) 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 default. • VPN - VPN Passthrough must be enabled if you want to allow VPN tunnels using IPSec, PPTP or L2TP protocols to pass through the router's firewall. • PPTP Pass-through - Point-to-Point Tunneling Protocol (PPTP) allows the Pointto-Point Protocol (PPP) to be tunneled through an IP network. If you want to allow PPTP tunnels to pass through the router, you can keep the default (Enabled). • 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.

•
Firewall
- A firewall protects your network from internet attacks.
•
Enable SPI Firewall
- SPI (Stateful Packet Inspection, also known as dynamic
packet filtering) 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 default.
•
VPN
- VPN Passthrough must be enabled if you want to allow VPN tunnels using IPSec,
PPTP 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. If you want to allow
PPTP tunnels to pass through the router, you can keep the default (Enabled).
•
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. If you
want to allow L2TP tunnels to pass through the router, you can keep the default
(Enabled).
•
IPSec Pass-through
- 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. If you want to allow IPSec
tunnels to pass through the router,
you can keep the default (Enabled).
