5.1.3 Options

The Options page allows you to enable/disable some advanced features supported by CBV704EW.

Check the option you want to use and click Apply button to enable the function(s). z WAN Blocking: To prevent others on the WAN side from being able to ping your CBV704EW. With WAN Blocking on, your CBV704EW will not respond to pings it receives, effectively “hiding” your gateway.

z Ipsec PassThrough: To enable IpSec type packets to pass through between WAN and LAN. z

PPTP PassThrough: To enable PPTP type packets to pass through between WAN and LAN. z Remote Config Management: To make the Web Management pages of your CBV704EW accessible from the WAN side. Page access is limited to only those who know the CBV704EW access password you set in the

Status--Security page.

When accessing the CBV704EW 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 CBV704EW’s Web Management page from a remote location. z 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. z UPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-topeer 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.

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.
