Hello, I'm new to NetXMS but it has attracted me and decided to set up it to monitor our and our client's network devices like switches and routers. First I did container structure for our default network and some clients networks. I had a problem with overlapping subnets, so had to create zones for each client site. Everything looks ok and looks nice but the problem is that now I'm not able to get the full L3 MAP it's not populating. Routers are monitored via WAN while switches are monitored via GRE + IPSec tunnels. I have connectivity to all monitored devices and I see a warning on any change, but I just can't get MAPs working. Any advice on how to fix it, I saw something about proxy nodes but didn't get to the end of how it works, any advice is appreciated a lot.
