Nut upsuser - Feb 2021 - Proxy upsmon

Hi,

I have the following Scenario:
The Devices are connected as shown here
USV <-> nut-server <-> Firewall_1 <-> Firewall_2
I have no Problem to get it working till Firewall_1.
The Problem is that Firewall_2 is not able to connect directly to 
nut-server.
I would like to setup upsd on the Firewall_1 to monitor the USV via the 
nut-server and then set the Firewall_2 to monitor the Firewall_1
Is this possible ?

Kind Regards
Mit freundlichen Gr??en

First, it would be good to get a clear understanding of your setup.  Is this 
correct?
