How to refresh DNS on XG Firewall?

HI, good day. If i change the WAN Link, with another ISP, is there a way to refresh the dns? for example in Windows i could do something like ipconfig /flushdns or even renew the IP, but, in this Firewall, how could i do this without restart the device? thanks a lot.

Did you change your DNS tab settings? Seems like that alone should do the trick.

Are your computers having issues resolving DNS / websites or what is the issue? This tab only gives the firewall a DNS to use but not the computers. Try the Diagnostics page and try to ping google.com to test if these settings are correct. Also, you can set one of them to 8.8.8.8 which is a free google dns server and resolves all internet sites.

The DHCP tab there will let you create a dhcp scope so that your computers get IP addresses, and it is also on that tab that you configure which DNS servers the computers should use.

Hi,

is your WAN interface using PPPoE and if it is then you will not be able to select DHCP.

As advised in other posts you can use the XG as you LAN network DNS server by adding it to the DHCP LAN configuration or manually configuring it in each device.
