Does IPSEC work through NATed connections?

Hi, we have a client that wants to connect via the public Internet to a branch office in another country. The branch only has a connection through a cable ISP, and they can give him a public IP, but they will NAT from the inside of the cable (10.X.X.X) network. Will IPSec work with this setup? I have had another experiences where this wouldn't work, but I still have my reservations.

Sure, NAT will work just fine. Port Address Translation or NAT-overload won’t.
