I have configured a remote agent trough the agent tunnel and linked the agent to a container in a zone. I have setup network discovery for the zone and selected the agent as the proxy node. In the agent logs, I can see the scan is being activated and lots of devices are found with both icmp and snmp scan, but nodes are not being added. Anyone who can guide me where to look for issues?
Where exactly you are checking for new nodes, under Infrastructure services or under Entire network?
You can enable debug, in server debug console:
debug poll.discovery 6
Then check server log, there should be some messages on what's happening.
To disable debug:
debug poll.discovery -1
Here is what I get in the log.

I've checked your initial message, do not truly understand what is meant by "linked the agent to a container in a zone".
Agent should be specified in Zone's properties on Communications page. Zones are found under "Entire network" (Network perspective).
From agent's side it's configuration should have
EnableProxy = yes
EnableSNMPProxy = yes
If issue still persist, please grep the log for 2-3 specific IP addresses so that we have full process for each of them.
I'm a novice user at NetXMS, so bear with me about technical terms, but link/binding or not, should not limit the ability to add discovered nodes.
Here is the log from a node with 192.168.1.205, which does not get added.
