I'm new to VLANs, so take that into consideration...

Lets say that I had a server set up to create a virtual interface that is set to be tagged as VLAN 3. For example, the following Debian config:

iface eth0.1 inet static
    address 192.168.1.1
    netmask 255.255.255.0

Now on my switch, lets say that I have the port that the aforementioned server connects to, set to VLAN 4...

Who wins? What are the packets tagged as, as viewed by the rest of the network?
