I try to install NS7_up1. Configuration - Network - Configure DNS servers - Primary DNS 220.127.116.11 Secondary DNS 18.104.22.168
Gateway - Web proxy - Enable proxy - Transparent -
Internet works, all sites are opened.
Gateway - Web proxy - Enable proxy - Transparent with SSL + Block HTTP and HTTPS ports
Sites are opened, but there is no web access to gmail mail. If you use Thunderbird, the mail works. Google.com opens. Gmail.com no.
In the local DNS network - DHCP windows server 2016. ip 192.168.1.4
If you use DNS as a DNS and DHCP server, the NS7 problem remains.
Help to solve the problem.
