Yes, they belong to the same subnet. 

Surprisingly, using the IP address in the node configuration for REMOTEPC worked!  Is there any reason you can think of that would cause NetXMS to send a broadcast (255.255.255.255) when using the name instead of the IP address?  My concern with using the IP address is for workstation monitoring where they use DHCP addresses that could change at any time.

Thank you very much for your assistance in troubleshooting this!

I'm running -D 9 as I'm assuming you want the debug information.  Nothing comes through on REMOTEPC when running a poll from the NetXMS server.  Although it appears the AGENTPROXY is attempting to setup some kind of proxy.  Maybe something with the 255.255.255.255 reference?  REMOTEPC is showing the unknown interface as having an IP address of 255.255.255.255.  When I added the node for REMOTEPC, I used the DNS name.

AGENTPROXY is assigned to the "Default" zone while REMOTEPC is assigned to the "Remote" zone.  Are there any other ports other than tcp/4700 needing to be open for this to work?

Thank you for the assistance.

Please forgive my first post as it is a little long winded.

I currently have NetXMS 1.2.7 installed and running properly for my local LAN.  I'm attempting to setup a proxy agent at a remote site and must be missing something.

I currently have a public IP address associated with the server (AGENTPROXY) at the remote site accepting tcp/4700 from our NetXMS Server (running Windows).  With this configuration I was able to add AGENTPROXY to NetXMS and properly poll the configuration.

Per previous posts and investigation, I modified the Agent configuration file for AGENTPROXY to include the following:

EnableProxy = yes
EnableSNMPProxy = yes

I then restarted the Agent on AGENTPROXY.  In addition, I set the EnableZoning option in NetXMS Server and created a new zone for this remote site.  I modified the Communication configuration of the zone to use AGENTSERVER for Default Agent Proxy, Default SNMP Proxy and Default ICMP Proxy.

I then installed the Agent software on REMOTEPC that has MasterServer pointing to AGENTPROXY.  I also have tcp/4700 open on REMOTEPC to allow connections from AGENTSERVER.

I added REMOTEPC in NetXMS as a new node, using AGENTPROXY as the proxy and assigning it to zone for the remote site.  With this configuration, I see REMOTEPC added to NetXMS but am unable to poll the configuration.  Here are the results of the poll:

[18.06.2013 12:04:48] **** Poll request sent to server ****

[18.06.2013 12:04:51] Node configuration was not changed after poll
[18.06.2013 12:04:51] **** Poll completed successfully ****

I'm trying to determine if this is an issue with NetXMS, my configuration or something with the network.  In doing so I am running nxagentd.exe -D 9 on AGENTPROXY and REMOTEPC.  I have also installed Wireshark on AGENTPROXY. 

When polling from the NetXMS server to REMOTEPC, I see traffic coming from the server to AGENTPROXY, but I see nothing being sent to REMOTEPC.  My assumption would be that the NetXMS Server talks to AGENTPROXY (hey I need to talk to REMOTEPC) and then AGENTPROXY would communicate directly with REMOTEPC, get the data and pass back to the server.

I feel I'm running around in circles at this point.  Any assistance or guidance is greatly appreciated.  Thank you.
