Here is a list of services/ports that I see most often. There are many more and I prolly forgot some. Check with the mgr/help forum and see what service and port(s) need to be open for each web activity you want to take part in. Then search the proto/port for known exploits. If it is an unsafe proto/port, then you get to decide if the risk is worth the gain.
