I setup the USG60 with a Static IP on the WAN1 with the Public DNS server addresses, but for some reason, Windows 2016 DNS stops working, Windows Server is also the DHCP, LAN1 has a private IP and the DHCP is disabled, what am I doing wrong?

    Hi @LouroeIT

    Can you provide your topology of your environment?

    Does your Windows server is behind USG ? Or located at other else?

    Hello, my Windows server is behind the USG, I have a simple LAN and I need to use the USG as my router as well.

    I fixed it, I set the LAN1 (P3) as a DHCP server and setup the DNS servers and every workstation is now on the internet.  It was a DNS issue, I just turned off the DHCP on my server and everything is back online.

    Hi @LouroeIT

    If you setup static IP address on your server, then DNS IP address is required.

    As your scenario, DNS IP address should set as USG interface IP address.
