Hello Dampyr,
    Cisco ASA can not register to Dynamic DNS services. You either have to configure atlantis router in routed mode and DDNS to register to dyndns, then forward possibly all ports (Some routers/modems call it BIMAP) or one-to-one map or at least forward UDP 4500, UDP 500 and TCP 10000 to ASA outside interface, or configure atlantis in bridged mode, let ASA outside interface get the public IP and install a DynDNS client on one of the computers located inside (a long time up server would be better) and let it do the registeration work.
