Just in case, did you also start the dummy driver?

This could solve my Problem.
Do you know in which Version the Repeater mode was added?
Whe i configure the UPS in ups.conf like this:
[ups]
driver = "dummy-ups"
port = "netvision at s"
and then Start the UPSD with upsd -D
I get this Output:
upsd -D
Network UPS Tools upsd 2.6.2
0.000000 listening on 0.0.0.0 port 3493
0.000198 Can't connect to UPS [ups] (dummy-ups-ups): No such file
or directory
So maybe the Version on the Firewall is to old

One solution can be a "dummy-ups" driver in proxy mode (and an upsd)
running on Firewall1 and so republishing data from a real device handled
by existing nut-server to a NUT client on Firewall2.
Note this can suffer from some lags compared to a real connection, but
e.g. a proxy like this allows us in lab to monitor real data from many nut
clients (instances in integration tests) although direct UPS connectivity
is way more limited (even networked ones can handle only so many clients)
:)
Technically these can be chained, we have proxies to proxies over vpn to
only have long-distance traffic once regardless of amount of running
tested clients.

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

In Firewall_2 you need upsmon to be able to talk to "nut-server"
machine
S.

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?

When you say "nut-server" one thinks of upsd, not upsmon. I guess you
mean "nut-client".

But does netcat S 3493 work on machine Firewall_2 ?

No problem, got a lot of that in context-switching lately :) Nice to hear it works, 2.6.2 is pretty old now...
