Select DNS Server Interface from available WAN interfaces OR enter static DNS
server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or
static IPoE protocol is configured, Static DNS server IP addresses must be entered.
DNS Server Interfaces can have multiple WAN interfaces served as system DNS
servers but only one will be used according to the priority with the first being the
highest and the last one the lowest priority if the WAN interface is connected.
Priority order can be changed by removing all and adding them back in again.
Click
Apply/Save to save the new configuration.
If is no IPv6 WAN interface is configured, a warning message system will pop up when
accessing DNS Server.
