Remote Config
Management
Mmakes 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. e.g., if the WAN IP
address is 157.254.5.7, you would navigate to
http://157.254.5.7:8080
to reach your gateway.
Multicast Enable
Enables multicast traffic to pass between WAN and
LAN. You may need to enable this to see some types of
broadcast streaming and content on the Internet
UPnP
Universal Plug and Play (UPnP) helps devices, such as
Internet appliances and computers, access the network
and connect to other devices as needed. UPnP devices
can automatically discover the services from other
registered UPnP devices on the network.
NAT ALG
NAT ALG (application layer gateways) allows
customized NAT traversal filters to be plugged into the
gateway to support address and port translation for
certain application layer "control/data" protocols such
as RSVP, FTP, TFTP, Kerb88, NetBios, IKE, RTSP,
Kerb1293, H225, PPTP, MSN, SIP, ICQ, IRC666x,
ICQTalk, Net2Phone, IRC7000, IRC8000 file transfer in
IM applications etc.
In order for these protocols to work through NAT or a
firewall, either the application has to know about an
address/port number combination that allows
incoming packets, or the NAT has to monitor the
control traffic and open up port mappings (firewall
pinhole) dynamically as required. Legitimate
application data can thus be passed through the
security checks of the firewall or NAT that would have
otherwise restricted the traffic for not meeting its
limited filter criteria.
