Hello Marco, Here in Firewall_1 you are running upsd only? Isn't it upsmon that
you should be running?
| Network B

| Firewall-2 with upsd 2.6.2 |

In Firewall_2 you need upsmon to be able to talk to "nut-server" machine S
My Problem is Firewall-2 can only reach Firewall-1.
I guess that Firewall_1 is supporting two networks, A and B, and that you cannot
get from a machine on network B to machine S on network A. Is this correct?
Do the firewall logs record any rejected traffic?
Firewall-1 can reach every Device.
On Firewall-1 the nut-server is configured as Monitor and the shutdown works
properly.
When you say "nut-server" one thinks of upsd, not upsmon. I guess you mean
"nut-client".
The Connection from Firewall-2 to Firewall-1 works via netcat.
But does netcat "nut-server" 3493 work on machine Firewall_2 ?
