◆ 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
states 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.
