10 • IP interface configuration
Setting the IP address and netmask
Each IP interface needs its explicit IP address and an appropriate net mask to be set. You can use the
ipaddress
interface configuration command to perform the following tasks:
•
Set the IP address to
ip-address
•
Set the network mask to
netmask
•
Enable IP processing for the IP interface
name
without assigning an explicit IP address
The
ipaddress
command offers the following options:
Mode:
Context IP. This command also places you in interface configuration mode.
Example:
Configure IP interface address and netmask
To set the IP address to
192.168.1.3
and net mask to
255.255.255.0
for the IP interface
lan
, use the following
commands in IP context configuration mode.
node(ctx-ip)[router]#interface lan
node(if-ip)[lan]#ipaddress 192.168.1.3 255.255.255.0
Configuring a NAPT DMZ interface
The NAPT allows one or more specific IP interfaces to be excluded from NAPT translations although their
traffic is routed through an IP interface to which a NAPT profile is bound. This configuration is usually neces-
sary, for DMZ networks connected to an Ethernet port, which uses public IP addresses.
Mode:
interface ip <if-name>
unnumbered
Enables IP processing on an interface without assigning an explicit IP address to the inter-
face.
ip-address
Specifies the IP address of the subscriber in the form A.B.C.D.
netmask
Specifies the network mask in the form A.B.C.D.
dhcp
Enables the DHCP client on this interface. For more information on DHCP-client configura-
tion refer to chapter 27,
“DHCP configuration”
on page 290.

If
no
napt-inside
is specified, the interface is excluded from
NAPT. if however
napt-inside
is specified, the interface will
be handled normally by the NAPT.
