Not -constantly- on -- but the client needs to run at the
frequency of the maximum delay you are willing to tolerate before
the IP is updated. For example, if you don't mind waiting half an
hour for dyndns to catch up with an IP address change, then the client
only needs to run every half an hour.

All the client has to know is your login name and password and the
relevant domain name. The client connects to dyndns.com and says
"I'm here!"... passing through the NAT translation to the outside IP
address as it does that. dyndns.com reads off sender's IP address
from the packet -- which will be the translated IP address. Which is
exactly the address that needs to be registered in the DNS tables.
It doesn't matter how many layers of translation that the client has
to go through, as long as the final translation is the one that
external systems should be using to contact you.
