Devs - Is there anyway to check if port is blocked on public network?

[Overcast]

Not sure if you could get that done - although... I found some posts on something called "Wimba Live Classroom" that seems to use port 5998...

lol

Now if it was me, I'd whine and say I use it for religious studies or something and see if they would allow outbound connections on it - that's more involved.

Might be better off getting dial-up or an AirCard if you really are going to need a connection where it's otherwise blocked. But maybe some other folks have some inventive ideas.
