Options Web Page
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 office 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 Config Management and then click 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...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
remote location.
Check Multicast Enable and then click 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.
IP Filtering Web Page
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.

MAC Filtering Web Page
This page enables you to enter the MAC address of specific PCs on your LAN that you wish to
NOT have outbound access to the WAN. As with IP filtering, these PCs can still communicate with
each other through the gateway, but packets they send to WAN addresses are blocked.

Port Filtering Web Page
This page enables you to enter ranges of destination ports (applications) that you don’t want
your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will
be blocked. For example, you could block access to worldwide web browsing (HTTP = port 80)
but still allow email service (SMTP port 25 and POP-3 port 110).
To enable
ltering, set Start
Port and End Port for each range, and click Apply. To block only one port, set both Start and End
ports the same.
