I have built the VMware images for the Smoothwall project, and if you go over to the community site you can get the new express 3 image from our site, the link is off the main page.
They work fine with a single NIC, this post is coming from behind such a VMware session now, but you could change the VMware settings to use multiple NIC's if you wanted without to much trouble. Basically you bridge the red SW NICs , and connect the Green NIC on a virtual internal network, which your host also uses. You can then use all of SW's proxies etc, and protect your machine. This does need a machine with plenty of RAM, and a good processor mind ;-)
If you need any help just post in my vmware post on the SW community site and I will help you fix it.
