A couple of weekends ago my home ISP took all of its subscribers and moved us from public IP to behind a big 10-dot NAT cloud. Of course, we had a couple small service outages getting there, but at the end of it, we now are on private IPSpace. Probably nobody noticed but me. =)

From what I’ve seen over the past couple of years, typically broadband ISPs have been going the filtering route. Most of them block incoming http, smtp, and maybe all the NetBIOS/AD stuff (at least if they’re smart). Now not only do I have that, but it has become a case of “we can’t get here from there”.

This is a fun one to deal with. I was very used to the public IP way. I had a couple of incoming services available like SSH and IMAP over SSL to get my PDA to work. Now I had to shift it all to my “real” server. I guess that’s the way I should have done it from the start.
