Re: Multiple DNS on IPConfig
Yes, that is correct. Remember to add also your DHCP IP address(es) since is the DHCP that lease you the IP and allows you to connect. Yes, trusted zone must be set to MEDIUM and not high (the default at install). Normally ZA automatically adds this information in the ZA zones unless you are using an old version or installing it without an active internet connection.
Also remember to run only 1 (one) firewall a time as well as 1 (one) active antivirus a time.
If you have still problems.... then please give more info on the system, exact version of ZA, security tools used (detailed list), OS version used, if it ever worked before, what the changes you have performed. The content of ZAlogs blocked items.... more information you post more likely someone will be able to help you.
Also note that if you have a valid license you can contact, free of charge, the official ZA technical support at the link in my signature.
