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.

5.6 Routing

5.6.1 IP Route

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.
