that are available for both public and in-network accesses (such as a company's public 

Web server). Packets incoming on a DMZ interface -- whether from a LAN or external 

source -- are subject to a level of protection that is in between those for public and private 

interfaces. 

Lower interface: EoA interfaces are defined in software, and then associated with lower-level 

software and hardware structures (at the lowest level, they are associated with a physical port 

- the WAN port). This field should reflect an interface name defined in the next lower level of 

software over which the EoA interface will operate. This will be an ATM VC interface, such as 

aal5-0. 

Config IP Address and Net Mask: The IP address and network mask you want to assign to 

the interface. If the interface will be used for bridging with your ISP and you will not be using 

the device as a router on your LAN, then you do not need to specify IP information. If you 

enable DHCP for this interface, then the Configured IP address will serve only as a request to 

the DHCP server. The actual address that is assigned by the ISP may differ if this address is 

not available. 

Use DHCP: When enabled, this setting instructs the device to accept IP information assigned 

dynamically by your ISP's DHCP server. If the interface will be used for bridging with your ISP 

and you will not be routing data through it, leave this checkbox unselected. 

Default Route: Indicates whether the ADSL/Ethernet router should use the IP address 

assigned to this interface, if any, as its default route for your LAN. This can be Enable or 

Disable. 

Gateway Address: The external IP address that the ADSL/Ethernet router communicates with 

via the EoA interface to gain access to the Internet. This is typically an ISP server. 

 

IP routes can be created on the ADSL/Ethernet router to specify where it should send 

data received on a particular interface. Routes specify the IP address of the next device 

interface or Internet destination to forward data to, given the ultimate destination of the data. 

A common type of route is a default gateway, which defines the IP address where all data 

is forwarded unless an IP route has been defined for the particular destination in question. 

Each time data is passed towards its destination from one Internet address to another, it is said 

to complete one hop.
