Chapter 11 Interfaces

NXC5200 User’s Guide

181

Interface Type Select to which type of network you will connect this interface. When

you select Internal or External the rest of the screen’s options
automatically adjust to correspond. The NXC automatically adds
default route and SNAT settings for traffic it routes from internal
interfaces to external interfaces; for example LAN to WAN traffic.

Select Internal to connect to a local network. Other corresponding
configuration options: DHCP server and DHCP relay. The NXC
automatically adds default SNAT settings for traffic flowing from this
interface to an external interface.

Select External to connect to an external network (like the Internet).

If you select General, the rest of the screen’s options do not
automatically adjust and you must manually configure a policy route
to add routing and SNAT settings for the interface.

Interface

Specify a name for the interface. It can use alphanumeric characters,
hyphens, and underscores, and it can be up to 11 characters long.

IP Address
Assignment

These IP address fields configure an IP address on the interface itself.
If you change this IP address on the interface, you may also need to
change a related address object for the network connected to the
interface. For example, if you use this screen to change the IP
address of your LAN interface, you should also change the
corresponding LAN subnet address object.

External or General. Select this to make the interface a DHCP client
and automatically get the IP address, subnet mask, and gateway
address from a DHCP server.

Address

This option appears when you set the Interface Properties to
External or General. Select this if you want to specify the IP
address, subnet mask, and gateway manually.

or you select Use Fixed IP Address.

Enter the IP address for this interface.

Subnet Mask

This field is enabled if you select Use Fixed IP Address.
