    I have a zone that contains:
    1x Linux node which is NATed and reached through a port forward on below firewall.
    1x firewall on edge
    8x switches that use the Linux node as proxy for SNMP/ICMP/etc.

    Linux node and switches are being monitored just fine.

    I cannot add firewall by public IP because the IP conflicts with the Linux node and duplicate add is prevented.
    I can add the firewall with its private IP, but then some hours later, NetXMS deletes it when it realises that the firewall's outside IP is detected as a duplicate of the Linux node.

    I could have sworn I'd succeeded at this in the past. I would think it's a fairly common configuration. Do I need to do something "special" to the Linux node to prevent the duplicate detection?

      In node properties -> Communicaitons there is checkbox "Communication through external gateway". If set, NetXMS will know that this is a forwarded port.

        Thanks, I've ticked that, re-added the firewall and will wait to see what happens...
