Yeah it can do that. And not just between your network and the internet, if you use multiple zones you can setup specific ports that are open between each network. For example you could allow access to a file server on the green network from the purple network but the purple network couldn't access any other clients on the green network.
Smoothwall uses colors to define the interfaces. Red is the internet, green is the main network on the inside. Orange is the DMZ and purple is the wireless network. Though you could use purple for something other than wireless if you wanted. Red and green are required, the other two are optional.
Smoothwall also has a proxy server with caching that you can turn on which can help if you have a low bandwidth connection. There is also anti-virus functionality to scan email to stop viruses before they even reach the clients. There is a VPN mod you can add in so you can VPN into your home network from the outside. There are also tons of monitoring functions. Back when I had to worry about monthly bandwidth usage the smoothwall was very helpful because I had a mod on it that tracked usage per IP address and could keep on eye on things.
There are other little things you can do too. Like on mine the DNS server configuration is setup to know what IPs my ISP uses for their custom search page if an address doesn't exist. That way instead of saying something exists and having that silly search page, it properly returns an address not found error.
Some of these things you can do with a consumer router running custom firmware like DD-WRT.
