I will have to describe this as I don't think I can use screenshots here.

* Run the setup command.
* Select Networking
* Select Drivers and card assignments
* Select OK to the question Do you wish to change these settings? at the bottom of the scrollable display box.
* Existing code will then say Restarting non-local network... but it will actually be running
/etc/rc.d/init.d/network stop red blue orange

Then you will have the page show with the assigned cards.
* Select Done without doing any thing else. This means that the
netaddresschange variable has not been set as no change was actually carried out but the red, blue and orange interfaces (if present) have all been stopped and are not restarted because no actual change was done.

I am thinking that the original code was thinking non-local meant everything that is not the network you are doing the setup from, which in most cases would be green. I checked in the git repo and that bit of code has been in IPFire since at least CU30.

Thinking a bit more about it as the main Network Restart (stop followed by start and unbound restart) occurs when any change has been carried out (netaddresschange variable is made equal to 1) then maybe that line

runcommandwithstatus("/etc/rc.d/init.d/network stop red blue orange",
  _("Networking"), _("Restarting non-local network..."), NULL);

should just be completely removed or if a change is actually made to the zone assigned to a mac address while the network is still running does this cause problems.

I will look at testing out the removal of that partial network stop (red, blue & orange but not green) and see what happens when running setup.

Let me know if I have not explained the above well enough.

Regards,

Adolf.
