SmartWare Software Configuration Guide 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:

	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 292.
Mode: Context IP. This command also places you in interface configuration mode.
	Step		Command	Purpose
1	node(ctx-ip)[router]#interface name		Selects the existing interface name, which shall be
				configured
2	node(if-ip)[name]# ipaddress {unnum-		Sets the IP address ip-addressand netmask net-
		bered (ip-address netmask) dhcp}		mask for interface name

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>

Step	Command	Purpose
1	[name] (if-ip)[if-name]# [no] napt-	If no napt-insideis specified, the interface is excluded from
	inside	NAPT. if however napt-insideis specified, the interface will
		be handled normally by the NAPT.
