Configuration of static routes and routing table, NAT/NAPT and VCs.
PPP user ID and password.
Security Support
Hidden by NAT. NAT opens a temporary path to the Internet for requests originating
from the local network. Requests originating from outside the LAN are discarded,
preventing users out-side the LAN from finding and directly accessing the PCs on the
LAN.
Port Forwarding with NAT. The 1 Port ADSL Router allows you to direct
incoming traffic to specific PCs based on the service port number of the incoming
request, or to one designated "DMZ" host computer. Forwarding of single ports or
ranges of ports are configurable.
Support URL Blocking. Prevent any LAN clients from accessing specific Internet site
by set- ting the URL keywords. The 1 Port ADSL Router will reject all those web site
whose URL names are matched or partially matched with the keywords.
Support MAC Filtering function. This function enable the administrator to control
the LAN client computers to access the Internet by the hardware MAC Address.
Content Filtering
Blocks unwanted traffic from the Internet to your LAN.
Blocks access from your LAN to Internet locations or services that you'd specified.
Logs security incidents. The 1 Port ADSL Router will log security events such
as blocked incoming traffic, port scans, attacks, and administrator logins.
Extensive Protocol Support
IP Address Sharing by NAT. The 1 Port ADSL Router allows several networked PCs
to share an Internet account using only a single IP address, which may be statically
or dynamically assigned by your Internet service provider (ISP).
Automatic Configuration of DHCP. The 1 Port ADSL Router dynamically assigns
network configuration information, including IP Address, WAN Gateway, Domain
Name Server ( DNS ) Addresses, ... etc. This greatly simplifies configuration of PCs
on your local network.
Dynamic DNS. This is a method of keeping a domain name linked to a changing IP
Address as not all computers use Static IP addresses. Typically, when a user connects
to the Internet, the user's ISP assigns an unused IP address from a pool of IP addresses,
and this address is used only for the duration of that specific connection.
PPP over Ethernet (PPPoE).
over Ethernet frames from the user to the ISP over the Internet. One reason PPPoE is
preferred by ISPs is because it provides authentication (username and password) in
addition to data transport. A PPPoE session can be initiated by either a client
application residing on a PC, or by client firmware residing on a modem or router.
PPTP (Point-to-Point Tunneling Protocol) – PPTP is a protocol ( set of communication
rules ) that allows corporations to extend their own corporate network through private
" Tunnels " over the public Internet. Effectively, a corporation uses a wide-area
network as a single large local area network. A company no longer needs to lease its
own lines for wide-area communication but can securely use the public networks. This
kind of interconnection is known as a virtual private network.
PPPoE is a method for the encapsulation of PPP packets
