OK, maybe I should clarify a little bit. The IP address that is bound to the X0 (LAN) port on my TZ210 does not change. It is always 192.168.1.99. It is only within NetXMS that shows the primary IP address as something from the Static IP pool for SSLVPN clients. The actual IP address on the device never changes. I can always pull up a web browser and administer the TZ210. But, within NetXMS, after the node's Primary IP address is changed from 192.168.1.99 to an IP from the static pool, NetXMS shows the node as "DOWN" and none of the DCI's work, presumably because NetXMS is trying to communicate via an IP address from within the static pool, and not the IP that is bound to the X0 port.
What is the mechanism used to determine a nodes Primary IP Address? Also, what polling occurs at regular intervals?
