Check the option you want to use and click Apply button to enable the
function(s).
 WAN Blocking: To prevent others on the WAN side from being able to
ping your CGA0112 . With WAN Blocking on, your CGA0112 will not
respond to pings it receives, effectively “hiding” your gateway.
 Ipsec PassThrough: To enable IpSec type packets to pass through
between WAN and LAN.
 PPTP PassThrough: To enable PPTP type packets to pass through
between WAN and LAN.
 Remote Config Management: To make the Web Management pages of
your CGA0112 accessible from the WAN side. Page access is limited to
only those who know the CGA0112 access password you set in the
Status--Security page.
When accessing the CGA0112 from a remote location, you must use
HTTP port 8080 and your IP address. This is the "WAN IP address" that
appears at the Basic--Setup page. For example, if this IP address were
211.20.15.28, you would navigate to http:// 211.20.15.28:8080 to reach
the CGA0112 ’s Web Management page from a remote location.
 Multicast Enable: To enable multicast traffic to pass through between
WAN and LAN. You may need to enable this to see some types of
broadcast streaming and content on the Internet, such as webcasting of a
popular live event.
 UPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-to-
peer network connectivity of PCs of all form factors, intelligent appliances,
and wireless devices. UPnP architecture leverages TCP/IP and the Web
to enable seamless proximity networking in addition to control and data
transfer among networked devices in the home, office, and everywhere in
between.
4.4.2 IP Filtering
The IP Filtering page enables you to enter the IP address ranges of PCs on
your LAN that you don’t permit to have outbound access ability to the WAN.
