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 IPSec,
PPTP, or L2TP protocols to pass through the Router’s firewall.
