Nethserver 7.4 unrestricted internet access

I need to make a rule for a machine to have unrestricted internet access type: ACCEPT loc: net
output iptables -vnL: 0 0 ACCEPT all - * *
It should not be released in “Hosts without proxy” because when I release there the application does not work. This machine read people’s fingerprints.
I have already simulated and created several rules but it does not work.
can anybody help me?
Thanks in advance for your attention.

Do you have a router between internet and your nethserver? So you could give the machine a manual IP config and set the gateway to the routers address.
