modify any configuration of NAT device.

a. Pass through method for H.323:

Gateway needs register to SK Series Gatekeeper to pass through NAT router.

b. NAT Traversal for SIP: Support STUN Client and Symmetric RTP to pass through NAT

router.

Network:

1. Network Address Translation (NAT): NAT allows multiple PCs to connect to an Internet

Service Provider (ISP) using a single Internet access account.

2. Firmware Upgrade (FTP Client): Using this FTP client to Upgrade software, you may easily

upgrade to the latest firmware whenever enhanced features are added.

3. Web (HTTP) Server: A Web browser is the most common tool used to surf the Internet. You may

use Microsoft’s Internet Explorer or Netscape’s browser etc, to configure the GW 200/400 /800

series routers as easily as surfing a website.

4. Dynamic Host Configuration Protocol (DHCP) Client on WAN Port: In most cable modem

environments, the Gateway supports a DHCP client on the WAN port. They can automatically get

IP network settings from a cable head-end access server.

5. Dynamic Host Configuration Protocol (DHCP) Server:This Gateway provide an easy-to-

configure function for your local IP network. It can automatically assign IP network configurations

for local PCs, such as IP address, IP netmask, gateway IP address, and Domain Name server etc.

6. Point-to-Point Protocol over Ethernet (PPPoE) Client Support: If you are a DSL user, the

router has a built-in PPPoE client for establishing a DSL link connection with the ISP. There is no

need to install a further PPPoE driver on your computers.

7. Smart QoS : The smart QoS provide stable voice quality while user access internet from

private LAN to internet at the same time. This device would start suppressing throughput au

tomatically when VoIP call proceed and keep full speed access when there is no VoIP traffic.

8. DDNS(Dynamic Domain Name Server): DDNS is a service that maps Internet domain names

to IP addresses. It allows you to provide Internet users with a domain name (instead of an IP

Address) to access your Virtual Servers.

9. Virtual Server : Remote Users can access services such as the Web or FTP at your local site

via public IP addresses can be automatically redirected to local servers configured with private IP

addresses.
