Virtual Interface Usage
 
Hola,
I need to ask about Virtual Interface, as i need to use my ethernet interface to act as two ethernet ports.
as i need to give eth0 an IP address and give eth0.5 another ip address, and make some natting and other issues.
Can i do that with the same interface ???

You can assign multiple ips to the same interface...

eth0
eth0:0
eth0:1

etc. Putting them on different networks doesn't work well though (or depending what you're doing exactly, at all.)

Most nic cards do support multiple interfaces but not all.

How couldn't they ?
Virtual interfaces are a TCP/IP stack (i.e. kernel) feature, not an Ethernet cards (driver/hardware) one.
