Public Internet connection security port check

[goLfie]

Anyone know a good way to check my firewall ports to make sure my laptop will be safe on a public connection?

I like to use http://www.canyouseeme.org/ for checking port security. Great for those trips to the airport or flights where you just aren't too sure about how good their network security is. Even around the office its nice to have so you can keep out nosy co-workers.
