Service License refresh sometimes use AUTO DNS

PeterUK

VPN300 V5.37(ABFC.0)

In DNS forwarder I have

* 192.168.53.12 VLAN53

* 192.168.53.4 VLAN53

And AUTO default that I don't want to use and have blocked then upstream with a switch

When you do a Service License refresh it will sometime use AUTO and will fail refresh it again then it works

This problem could be solved by this

Update, we will add a option in interface to control request DNS option in next generation firewall(next platform).

Hi @PeterUK ,

Do you mean a setting to disable request DNS option when wan interface is DHCP or PPPoE?

PeterUK
