Advance Settings
Click this button to display a greater or lesser number of configuration fields.
General Settings
Enable Interface Select this to enable this interface. Clear this to disable this interface.
Interface Properties
Interface Type This field is read-only.
internal - is for connecting to a local network. Other corresponding configuration
options: DHCP server and DHCP relay. The ISG50 automatically adds default SNAT
settings for traffic flowing from this interface to an external interface.
external - is for connecting to an external network (like the Internet). The ISG50
automatically adds this interface to the default WAN trunk.
Interface Name Specify a name for the interface. It can use alphanumeric characters, hyphens, and
underscores, and it can be up to 11 characters long.
Port This is the name of the Ethernet interface’s physical port.
Zone This is the zone to which this interface belongs. You use zones to apply security settings
such as firewall and remote management.
MAC Address This field is read-only. This is the MAC address that the Ethernet interface uses.
Description Enter a description of this interface. It is not used elsewhere. You can use alphanumeric
and
()+/:=?!*#@$_%- characters, and it can be up to 60 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.
Get
Automatically
This option appears when Interface Properties is external. Select this to make the
interface a DHCP client and automatically get the IP address, subnet mask, and
gateway address from a DHCP server.
Use Fixed IP
Address
This option appears when Interface Properties is external. Select this if you want to
specify the IP address, subnet mask, and gateway manually.
IP Address Enter the IP address for this interface.
Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask
indicates what part of the IP address is the same for all computers in the network.
Gateway This option appears when Interface Properties is external. Enter the IP address of
the gateway. The ISG50 sends packets to the gateway when it does not know how to
route the packet to its destination. The gateway should be on the same network as the
interface.
Metric This option appears when Interface Properties is external. Enter the priority of the
gateway (if any) on this interface. The ISG50 decides which gateway to use based on
this priority. The lower the number, the higher the priority. If two or more gateways
have the same priority, the ISG50 uses the one that was configured first.
