My ISP changed my IP about 5 days ago. DynDNS that points to my local nameserver updated quickly and that works. But the locally resolved names are not appearing to the outside world any more. They resolve inside my local network but not outside. I manually updated the IP's in ISPConfig 4 days ago. This should have been enough time to propagate. It has all been working fine for a year, including a couple of IP changes. Can people give me clues on what to check? Thanks.
