PC Concepts ADSL2+ Manuale Utente

 

Multiple DNS addresses are useful to provide alternatives when one of the servers is down 

or is encountering heavy traffic. ISPs typically provide primary and secondary DNS addresses, 

and may provide additional addresses. Your LAN PCs learn these DNS addresses in one of 

the following ways:

Statically: If your ISP provides you with their DNS server addresses, you can assign the 

addresses to each PC by modifying the PCs' IP properties.

Dynamically from a DHCP pool: You can configure the DHCP Server feature on the 

ADSL/Ethernet router and create an address pool that specify the DNS addresses to be 

distributed to the PCs. 

 

The ADSL/Ethernet router is capable of sending and receiving information in a variety of 

protocol formats. The Blocked Protocols feature enables you to prevent the ADSL/Ethernet 

router from passing any data that uses a particular protocol. Unlike the IP Filter feature, you 

cannot specify additional criteria for blocked protocols, such as particular users or destinations. 

However, when you are certain that a particular protocol is not needed or wanted on your 

network, this feature provides a convenient way to discard such data before it is passed.
