The ISP I am using does have NAT, but I was able to disable the NAT using the modem setting. (When they replaced the modem, I told them what setting I changed and they were able to put that setting into the new modem too) It is a dynamic address, but I can accept incoming connections and the IP address rarely changes (although it has happened before).
