•
Firewall
- A firewall protects your network from Internet attacks.
•
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 default.
•
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.
•
PPTP Passthrough
- Point-to-Point Tunneling Protocol (PPTP) allows the Point-
to-Point Protocol (PPP) to be tunneled through an IP network. If you want
to allow PPTP tunnels to pass through the router, you can keep the default
(Enabled).
•
L2TP Passthrough
- Layer 2 Tunneling Protocol (L2TP) is the method used to
enable Point-to-Point sessions via the Internet on the Layer 2 level. If you want
to allow L2TP tunnels to pass through the router, you can keep the default
(Enabled).
