As Roland suggested, very likely via UDP/1900. This will obviously be disclosed in advance to customers and tested thoroughly. I believe a few other ISPs have already taken this step. And is this practice Open Internet friendly? Port blocking is considered a form of reasonable network management provided it can be justified by security or operational stability reasons. Of course it must also be transparently disclosed and so on. Jason
