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

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 Firewall_2 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 S 3493 work on machine Firewall_2 ?
