      I need to move a VLAN to a different interface during a testing period of a new Network appliance. One the Vlan is assigned to the different Interface we lose DNS hence no internet access.

        Is this "different interface" enabled? Do you have any "allow interface to any" firewall rules on this interface? Is your DHCP server enabled on this interface?

          The interface is enabled. DHCP is not required on this interface as a Windows server server is providing it. Rules are based on VLANS not interfaces so the Rules follow the re-assignment of the vlan to a different interface. DNS is failing when it's on the different interface. orig int = igb0 new int = igb3.
