I recently upgraded f40->f42. Had issues (see my earlier thread) which I 
"fixed"...

While dealing with that other issue I found that while the server was working 
just fine,
other machines (on a wired connection) still cannot access the internet.

After looking everywhere, and digging into my iptables rules and such, I 
discovered that NAT is not being set up.

I added a rule to my firewall script
        iptables-legacy -t nat -A POSTROUTING -o eth1 -j MASQUERADE
eth0 is the local network, eth1 sees the internet.
Things work now.

In f40 NAT was always being set up automatically. Is it a network manager issue?

One day I will learn how to set up firewall rules in the "new way".
