• Firewall—A firewall protects your network from the outside world. Here you can enable or disable the router’s firewall.
- 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 factory default. If you want all the computers on the LAN exposed to the outside world, you can disable it.
• VPN—VPN Passthrough must be enabled if you want to allow VPN tunnels using VPN protocols to pass through the router.
- PPTP Passthrough—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.
- 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 router, click Enable.
