• Security, Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched to
only those confidential users within the VLAN.
• Cost Reduction, VLANs can be used to create multiple broadcast domains,
thus eliminating the need of expensive routers.
• Port-based (or port-group) VLAN is the common method of implementing a
VLAN, and is the one supplied in the Switch.
• QoS: QoS gives you full control over which types of outgoing data traffic should be
given priority by the Router, ensuring important data like gaming packets move
through the Router at lightning speed, even under heavy load. The QoS features are
configurable by source IP address, destination IP address, protocol, and port. You can
throttle the speed at which different types of outgoing data pass through the router, to
ensure P2P users don't saturate upload bandwidth, or office browsing doesn't bring
client web serving to a halt. In addition, or alternatively, you can simply change the
priority of different types of upload data and let the router sort out the actual speeds.
• Domain Name System (DNS) relay: provides an easy way to map the domain name
(a friendly name for users such as www.yahoo.com) and IP address. When a local
machine sets its DNS server with this router's IP address, then every DNS conversion
requests packet from the PC to this router will be forwarded to the real DNS in the
outside network. After the router gets the reply, then forwards it back to the PC.
• Dynamic Domain Name System (DDNS): The Dynamic DNS service allows you to
alias a dynamic IP address to a static hostname. This dynamic IP address is the WAN
IP address. For example, to use the service, you must first apply an account from this
free Web server http://www.dyndns.org/. There are more than 5 DDNS servers
supported.
• PPP over Ethernet (PPPoE): Provide embedded PPPoE client function to establish a
connection. Users can get greater access speed without changing the operation
concept, sharing the same ISP account and paying for one access account. No
PPPoE client software is required for the local computer. The Always ON, Dial On
Demand and auto disconnection (Idle Timer) functions are provided too.
• Virtual Server: Users can specify some services to be visible from outside users. The
router can detect incoming service request and forward it to the specific local
computer to handle it. For example, users can assign a PC in a LAN acting as a WEB
server inside and expose it to the outside network. Outside users can browse an
inside web server directly while it is protected by NAT. A DMZ host setting is also
provided to a local computer exposed to the outside network, Internet
• Rich Packet Filtering: Not only filters the packet based on IP address, but also based
on Port numbers. It also provides a higher-level security control.
• Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the
DHCP client can get an IP address from the Internet Server Provider (ISP)
automatically. In the LAN site, the DHCP server can allocate up to 253 client IP
addresses and distribute them including IP address, subnet mask as well as DNS IP
address to local computers. It provides an easy way to manage the local IP network.
