Hi Roger,
here is a Diagramm of the Connections
+----------------------------+ +----------------------------+
| Socomec UPS | |nut-server |
| only capable of SNMP |-----------|Ubuntu Server 20.04 |
| | |with upsd 2.7.4 |
| | | |
+----------------------------+ +----------------------------+

| Firewall-1 with upsd 2.6.2 | |
| without SNMP Support |----------------------+

+-----------------------------+
| |
| Firewall-2 with upsd 2.6.2 |
| without SNMP Support |
| |
+-----------------------------+
My Problem is Firewall-2 can only reach Firewall-1.
Firewall-1 can reach every Device.
The Connection from Firewall-2 to Firewall-1 works via netcat.
On Firewall-1 the nut-server is configured as Monitor and the shutdown
works properly.
I tried to configure this in the ups.conf on Firewall-1
[ups]
driver = "nutclient"
port = "netvision at nut-server"
But on start of the upsd i get the Error
Can't connect to UPS [ups] (nutclient-ups): No such file or directory

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

Sorry, the ascii art was mangled. I'll try again.
