I have installed a FreeNAS under VMware Player and I’m trying to access it using the web GUI (HTTPS / 443). If I pause Avast then it works immediately. But when I check the firewall logs for blocked traffic, I see no connections to this FreeNAS on port 443. Which component of Avast would be blocking this kind of traffic?
Set the Avast Firewall to private mode/network and reboot.
