Managing DNS servers

You can add up to three DNS servers to the system configuration. The DNS server is used by the captive portal when it forwards queries on the Exclude List. (For more information about the captive portal and the Exclude List, see “Captive portal and Exclude List” on page 386.)

To manage DNS servers in the system configuration, select the System > Servers > DNS Servers tab. The DNS Server Table appears (see Figure 150).
