Advanced Web Page Group
Options Web Page (Fig. 18)
This page allows you to enable/disable some features of the
Wireless Cable Gateway. Check WAN Blocking and then Apply to
prevent others on the WAN side from being able to ping your
gateway. With WAN Blocking on, your gateway will not respond
to pings it receives, effectively “hiding” your gateway.
Check Ipsec Pass Through and then Apply to enable IpSec type
packets to pass WAN <=> LAN. IpSec (IP Security) is a security
mechanism used in Virtual Private Networks (VPNs). E.g., your
employer may offer VPN connectivity to your office network to
provide security.
Click PPTP Pass Through and then Apply to enable PPTP type
packets to pass WAN <=> LAN. PPTP (Point to Point Tunneling
Protocol) is another mechanism sometimes used in VPNs.
Click Remote Config Management and then Apply to make the
configuration web pages in your gateway accessible from the
WAN side. Then you could, for example, access your home
gateway configuration from your workplace, if that location
also had Internet connectivity. Page access is limited to only
those who know the gateway access password you set using the
Status...Security web page.
Click Multicast Enable and then Apply to enable multicast
traffic to pass WAN <=> 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.
