Poll external networks without NAT


I have a LibreNMS in a Docker container to poll my network devices, but I need to poll some external devices, I use to NAT the public IP address to arrive the remote devices.

The problem is that sometimes there are more than one remote device to poll. I could execute some kind of proxy or remote poller, but I need to visualize all data in one central LibreNMS server.

Is it possible to install a remote poller and not open 5 or 6 SNMP NAT in the remote router?

Thanks for your help.

Kind regards.
