Figure 5-41 Basic Security

Firewall - Here you can enable or disable the Device's firewall.

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 it.

VPN - VPN Passthrough must be enabled if you want to allow VPN tunnels using VPN protocols to pass through the Device.

PPTP Passthrough - PPTP (Point-to-Point Tunneling Protocol) allows the Point-to-Point Protocol (PPP) to be tunneled through an IP network. To allow PPTP tunnels to pass through the Device, click Enable.

L2TP Passthrough - L2TP (Layer Two Tunneling Protocol) 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 Enable.

IPSec Passthrough - IPSec (Internet Protocol security) is a suite of protocols for ensuring private, secure communications over IP (Internet Protocol) networks, through the use of cryptographic security services. To allow IPSec tunnels to pass through the Device, click Enable.

ALG - It is recommended to enable Application Layer Gateway (ALG) because ALG allows customized Network Address Translation (NAT) traversal filters to be plugged into the gateway to support address and port translation for certain application layer "control/data" protocols such as FTP, TFTP, H323 etc.

FTP ALG - To allow FTP clients and servers to transfer data across NAT, click Enable.
