Diladele as Transparent Proxy for specific vLAN only

Using this guide I want to configure filtering for a specific vLAN only and not my entire network. I would assume most of the steps are similar (specify the vlan interface instead of the ether2) but possibly something additional might be needed as well that I may be missing or lacking? Any help would be great! Thanks!
