Firewall issues

Hello Sam.
Please check if AVG firewall is configured with below recommended settings or not.
Open AVG Internet Security->Menu->Settings->Components->Firewall->Customize->Network Profile and change it to Private.
Open AVG Internet Security->Menu->Settings->Components->Firewall->Customize->Policies->System Rules and set all rules to "Enabled".

I am an engraver.  I connect an engraving machine to my computer via ethernet cable.  The machine tools program does not connect to the machine unless I turn off the firewall.  Is there a setting somewhere in the firewall that I can change so I don't have to shut off my firewall?

Same issue after re-install.

Thanks Avinash for the tip but still not connecting.  When I try to change the network profile to private and then save then I go back in to the setting it still shows as public.
