Hasn't been a PITA for me, or any of my users that I know of.

Sure, it's problematic if you want to run a server open
to the public. But that's most likely problematic with
your ISP's AUP anyway.

The first problem I came across was it blocked FTP. You had to use passive FTP to get by it, but back in those days we used FTP apps and they didn't support it. Now, it gets in the way of VoIP and some online games. You have to use another hack, called STUN, to make them work.
