Billion Electric Company 7300M User Manual

Domain Name System Relay  

Domain Name System (DNS) relay provides an easy way to map a domain name with a 

user-friendly name such as www.billion.com with an IP address. When a local machine sets 

its DNS server to the router’s IP address, every DNS conversion request packet from the PC 

to this router is forwarded to the real DNS on the outside network.   

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. To use the service, you must first apply for 

an account from a DDNS service such as http://www.dyndns.org/.  

The BiPAC 7300M provides an embedded PPPoE client function to establish a connection. 

You get greater access speed without changing the operation concept, while sharing the 

same ISP account and paying for one access account. No PPPoE client software is required 

for the local computer. Automatic Reconnect and Disconnect Timeout (Idle Timer) functions 

are also provided. 

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, customer information, or 

management information move through the router ay 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. 

You can specify which services are visible to outside users. The router detects an incoming 

service request and forwards it to the specific local computer for handling. For example, you 

can assign a PC in a LAN to act as a Web server inside and expose it to the outside network. 

Outside users can browse inside the web server directly while it is protected by NAT. A DMZ 

host setting is also provided for local computers exposed to the outside Internet network. 

      Dynamic Host Configuration Protocol (DHCP) Client and Server 

On a WAN site, the DHCP client obtains an IP address from the Internet Service Provider 

(ISP) automatically. On a LAN site, the DHCP server allocates a range of client IP 

addresses, including subnet masks and DNS IP addresses and distributes them to local 

computers. This provides an easy way to manage the local IP network.
