5. Firewall, Failover and OOB Access Override DNS is available for PPP devices, such as modems. Override DNS allows the use of alternate DNS servers from those provided by your ISP. For example, an alternative DNS may be required for OpenDNS used for content filtering. • To enable Override DNS, check the Override returned DNS Servers box. Enter the IP of the DNS servers into the spaces provided. Note: By default, the advanced console server supports automatic failure-recovery that reverts it back to its original state prior to failover (firmware version 3.1.0 and later). The advanced console server continually pings probe addresses while in original and failover states. The original state will automatically be set as a priority and reestablished following three successful pings of the probe addresses during failover. The failover state will be removed once the original state has been re-established. 5.4 OOB Broadband Ethernet Access The console servers have a second Ethernet port that can be configured for alternate and OOB (out-of-band) broadband access. With two active broadband access paths to these advanced console servers, you can still access it through the alternate broadband path in the event you are unable to access through the primary management network (LAN1, Network or Network1). • On the System: IP menu, select Management LAN Interface and configure the IP Address, Subnet Mask, Gateway and DNS with the access settings that relate to the alternate link. • Ensure when configuring the principal Network Interface connection, the Failover Interface is set to None. 82
