Not offhand, it' the kind of thing that's easily abused, tho there are a
few places that can do that kind of thing for a fee...after they confirm
who you are...

depends on what kind of firewall, if it's say, a linux machine and you can
run the scan from it, you can scan your network side interface (via that
ip) and got most, tho, not all of the info you would from outside...

scanning from inside the firewall is not as pointless as you might think,
it's often good to know what can leak out too...

Eg anything open on the inside probably shouldn't also have a path
outside...

(If you like i can scan it for you and email you the result, provided i
can reasonably confirm it's your machine ;)
