I have similar setup. There is no problem at all with DynDNS.

You do not say how are you connecting to your ISP. In my case, I am on
cable, I have an SMC Barricade wireless router, on which I have
configured redirection of port 22 to the address I get - via DHCP -
from the router (which in itself gets it's routed IP address from the
cable modem again via DHCP, and which is configured to update my
DynDNS address when rebooted - so I have to reboot it from time to
time when I get mail from DynDNS that my address is expiring).

I got the log, but I don't think it is interesting at all in this case.

I see you are trying to connect as root and there is nothing changed
in sshd_config. By default, we have

PermitRootLogin no

there. This is not your problem, though. Yet.
