Yasha,
This is the article I originally used to create my VLANs:
http://www.cyberciti.biz/tips/howto-configure-linux-virtual-local-area-network-vlan.html
I am not find anything I missed. But, it is much better written
than my stuff, so it should be worth reviewing. If you find something
I missed, please let me know.
