I will use 192.168.0.1/24 for the purposes of this guide. This is the standard ip range to use for local home networks. 
Go to the "Interfaces Activated at Boot Time" tab and click eth_SAFE to configure it if it is there already. 
If it isn't there already (it probably isn't) then click "Add a new interface". Enter the following details:

"Name" - eth1
"IP Address" - Make sure the "Static" radio button is checked, and enter 192.168.0.1 into the text box.
"Netmask" - Should be 255.255.255.0
"Broadcast" - 192.168.0.255
"Activate at boot?" - Set to yes 

Then click "Create". Check the radio button next to the new interface you created and click "Apply"
 to activate those settings. Great! The two network interfaces are now totally configured.

 

Någon som vet varför det inte fungerar?
