Before I starting on the subject on this article I wish to highlight some important changes intoduced in the recent firmware releases starting 4.3.4-R8 and beyond. In case users are finding difficulty accessing their devices post an upgrade, they must review this information and proceed.
Note 1. By default, http access is disabled. Only https is allowed.
Note 2. By default, UI access over WAN is disabled for security concerns. Can be enabled if required.
Note 3. By default, SNMP access over WAN interface is disabled for security concerns. Can be enabled if required.
It is recommended to change the administrator password before enabling any one of the above.
Below is the list of important configuration parameters for R-series along with their descriptions.
These can be pushed via the "User Defined Overrides" in cnMaestro. For details refer to the article below.
