Since upgrading my 5.0 to 5.1.2, the system doesn't handle ip address changes. It seem that the system doesn't "get" that the address has changed. The configuration reports the old address, and the dynamic dns service isn't updated. When I update the dns manually through their web interface, my server is still unavailable from the Internet. it responds to pings to it's hostname, but ftp and incoming e-mail doesn't work. If I change the configuration to static ip, using the latest dhcp address from my isp, it works correctly. When I change back to dynamic ip, it still works, provided the address hasn't changed. As soon as the address changes, however, the problem comes back.
Any thoughts on this?
