Security
The Security function is available only in AP router mode and AP client router (WISP Client) mode.
Stateful Packet Inspection (SPI) is a firewall that keeps track of the state of network connections (such as
TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate
packets for different types of connections. Only packets matching a known active connection will be
allowed to pass through by the firewall and others will be rejected. SPI Firewall is enabled by factory
default.
SPI Firewall Check the Enable box to use the SPI Firewall function. If forwarding rules are
enabled at the same time, the device will give priority to meet forwarding
rules.
Ping
WAN Ping Forbidden: The default setting is disabled. If enabled, the
device will not reply the ping request originates from Internet.
LAN Ping Forbidden: The default setting is disabled. If enabled, the device
will not reply the ping request originates from local network.
VPN
A VPN is created by establishing a virtual point-to-point connection through
the use of dedicated connections, virtual tunneling protocols, or traffic
encryptions. Through VPN you can access your private network over Internet. A
virtual private network connection across the Internet is similar to a wide area
network (WAN) link between sites. From a user perspective, the extended
network resources are accessed in the same way as resources available within
the private network.
When hosts in the local area network want to visit the
remote virtual private network using virtual tunneling protocols
, the
corresponding VPN protocol should be enabled.
PPTP Passthrough - PPTP (Point-to-Point Tunneling Protocol) allows the
Point-to-Point Protocol (PPP) to be tunneled through an IP (Internet Protocol)
network. Check the box to allow PPTP tunnels to pass through the Device.
L2TP Passthrough - L2TP (Layer Two Tunneling Protocol) is the method
used to enable Point-to-Point connections via the Internet on the Layer
Two level. Check the box to allow L2TP tunnels to pass through the Device.
