¾ 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.
