We do not have DNS resolution when connected Client VPN. We have a MX250, firmware MX 14.40.  Our Client VPN configuration is the default "Use Google Public DNS".  When connected in our Client VPN subnet, ipconfig shows the DNS servers are as expected, 8.8.8.8 and 8.8.4.4. DNS resolution does not work (ping, RDP, browser, etc). My client device is Win10 19041.508. It had the issue with the prior Win10, 18363. What am I missing? Thank you.  -Greg ... View more
