I think "residential" service can opt-out too. It certainly should be able to. It's sold as a preventative measure, you certainly shouldn't have to pay extra to have certain ports open.<br><br>Some people run mail services for their families... websites... even old timey telnet BBS's. I understand blocking ports to generally keep botnets and open relays off your network. And I agree - as long as those of us who don't require said measures aren't forced into them. It should be the case that savvy people make better of their resources - not guiltily accept a penalty for being an advanced user...<br>

</div> If it's a business grade service, just ask them to unblock it. Just<br>
switched over one of my clients and there's no blocking what so ever.<br>

If you're running your office on a residential service, shrug, bone up<br>
on IPv6 and find someone who will forward.<br>
