To use the NiagaraAX implementation of DDNS you need to do the following:
-
Buy a service account from TZO (Tzolkin Corporation), to-date the only approved DDNS provider. Accounts are available for 1- and 2-year durations—and a pre-purchase 30-day free trial is also offered. (At the update time of this document, this is no longer possible—see Note.)
The JACE platform’s Niagara DDNS configuration is for the “DDNS client” that works with the TZO dynamic DNS servers—you do
not need to download any additional DDNS client software.
-
At the JACE, you also require Internet connectivity via an ISP (Internet Service Provider). Depending on the installation scenario, this may range from a “dialup ISP” to an ISP provider via a cable or DSL modem (either directly connected to the JACE, or to a routed-LAN upon which the JACE sits). See Example DDNS scenarios for more details.
If the JACE is installed on a LAN served by a router, often you can use “built-in” DDNS support of the router, with either TZO as the DDNS provider, or another DDNS provider (if supported by the router). In this case, you do not configure the JACE for Niagara DDNS. Instead, you must follow the necessary configuration for DDNS operation through the router, with the JACE as the “exposed” node on the LAN.
Refer to the router documentation for specific details on this configuration. Also, see the LAN connected DDNS scenario for a topology diagram and related discussion about this configuration (when using Niagara DDNS).
