Advanced
1. Options
This page allows you to enable/disable some features of the Wireless Gateway.
Fig. 17
WAN Blocking
prevents others on the WAN side from being able to ping your gateway. With WAN
Blocking enabled, your gateway will not respond to pings it receives, effectively ―hiding‖ your
gateway.
Ipsec PassThrough
enables IpSec type packets to pass WAN
LAN. IpSec (IP Security) is a
security mechanism used in Virtual Private Networks (VPNs).
PPTP PassThrough
enables PPTP type packets to pass WAN
LAN. PPTP (Point to Point
Tunneling Protocol) is another mechanism sometimes used in VPNs.
Remote Config Management
makes the configuration web pages in your gateway accessible from
the WAN side. Note that page access is limited to only those who know the gateway access password.
When accessing your gateway from a remote location, your must use HTTP port 8080 and the WAN
IP address of the gateway. For example, if the WAN IP address is 157.254.5.7, you would navigate to
to reach your gateway.
Multicast Enable
enables multicast traffic to pass WAN
LAN. You may need to enable this to see
some types of broadcast streaming and content on the Internet.
UPnP
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can automatically discover

the services from other registered UPnP devices on the network.
NatSip Alg Enable
feature enabled by default. While ALG could help in solving NAT related problems in client
LAN side. An ALG understands the protocol used by the specific applications that it supports and does a protocol
packet-inspection of SIP traffic through it. A NAT router with inbuilt SIP ALG can re-write information within the
SIP messages (SIP headers and SDP body) making possible signaling and audio traffic between LAN client and
outside SIP endpoint.
2. IP Filtering
This page
enables you to enter the IP address ranges of PCs on your LAN that you don’t want to have outbound access to
the WAN. These PCs can still communicate with each other on your LAN, but packets they originate to WAN addresses
are blocked by the gateway.
