Re: Whats the point of home SIP anyway?
"At this moment, to me the question is not "why would home user want SIP" - it is "why not want it", with one possible answer "lack of skills and motivation to learn". Which is pretty lame on ElReg, I think you will agree."
Yes, except this article demonstrates how fraught with potential pitfalls this area is. I am pretty technical and looking at my home network setup would scare and confuse any joe user not familiar with it (much like that of many reg readers I guess) but I don't know much about this stuff and on the basis of this story would certainly avoid it unless I'd done a ton of research.
I too would assume that "block all ports" means just that. The argument that it needs to be opened for the service to work is not a valid one in my view, because in that case the person doing so would at least be aware that they had opened a port, and could consider the implications.
