Advanced Web Page Group
Options Web Page (Fig. 25)
This page allows you to enable/disable some features of the Wireless Cable Gateway. Check WAN
Blocking and then click 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 click 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 offi ce network to provide security.
Check PPTP Pass Through and then click Apply to enable PPTP type packets to pass WAN <=>
LAN. PPTP (Point to Point Tunneling Protocol) is another mechanism sometimes used in VPNs.
Check Remote Confi g Management and then click Apply to make the confi guration web pages
in your gateway accessible from the WAN side. Then you could, for example, access your home
gateway confi guration 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...Password web page.
This function works only if your gateway is in the RG mode. When accessing your gateway from
a remote location, you must use HTTP port 8080 and your IP Stack 3 address. This is the "WAN IP
address" that appears at the Network...WAN page. For example, if this IP address were 157.254.5.7,
you would navigate to http://157.254.5.7:8080 to reach your gateway from a remote location.
