WAN Blocking
prevents others on the WAN side from being able to ping your gateway. With
WAN Blocking enabled, your gateway will not respond to pings it receives, effectively “hiding”
your gateway.
±
Ipsec PassThrough
enables IpSec type packets to pass WAN
²
LAN. IpSec (IP Security) is a
security mechanism used in Virtual Private Networks (VPNs).
±
PPTP PassThrough
enables PPTP type packets to pass WAN
²
LAN. PPTP (Point to Point
Tunneling Protocol) is another mechanism sometimes used in VPNs.
±
Remote Config Management
makes the configuration web pages in your gateway accessible
from the WAN side. Note that page access is limited to only those who know the gateway access
password. When accessing your gateway from a remote location, your must use HTTP port 8080
and the WAN IP address of the gateway. For example, if the WAN IP address is 157.254.5.7, you
would navigate to
to reach your gateway.

This page enables you to enter the MAC address of specific PCs on your LAN that you do not wish to
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.

Filtering
This page allows 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 port filtering, set Start Port and End Port for
each range, and click Apply. To block only one port, set both Start and End ports with the same value.
