This page allows you to configure the accessible features.
To enable a feature, click the appropriate check box until it is “checked”. When you
are satisfied with your selections, click on the Apply button. These features can be
modified on the fly without a system reset.
“WAN Blocking” prevents the CMRG or the PCs behind it from being visible to the
WAN. For instance, pings to the CMRG‟s WAN IP address or the PCs behind it are
not returned. Therefore, it will be more difficult for hacker to discover your WAN IP
address to begin an attack on your private LAN.
“IpSec” and “PPTP” (Point-to-Point Tunneling Protocol) pass-through modes enable
these protocols to be used through the CMRG such that a VPN device (or software)
may communicate properly with the WAN.
“ Remote Configuration Management” allows the CMRG to be administered
(configured) from the WAN via surfing to the WAN IP address on port 8080 of the
CMRG from anywhere on the Internet (e.g. at the browser URL window enter
http://WanIPAddress:8080/ to access the CMRG remotely).
