• Low (Rate: 10 KB/s. Time Period: 240 seconds.)
• Custom (Rate range: 1-100 KB/s. Time Period range: 10-300 seconds.)
Time: Fail back only after a set period of time. (Default: 90 seconds. Range: 10-300 seconds.) This is a good setting if you have a primary wired
WAN connection and only use a modem for failover when your wired connection goes down. This ensures that the higher priority interface has
remained online for a set period of time before it becomes active (in case the connection is dropping in and out, for example).
Disabled: Deactivate failback mode.
Immediate Mode: Fail back immediately whenever a higher priority interface is plugged in or when there is a priority change. Immediate failback
returns you to the use of your preferred Internet source more quickly which may have advantages such as reducing the cost of a failover data plan,
but it may cause more interruptions in your network than Usage or Time modes.
IP Overrides IP overrides allow you to override IP settings after a device's IP settings have been configured.
Only the fields that you fill out will be overridden. Override any of the following fields:
• IP Address
• Subnet Mask
• Gateway IP
• Primary DNS Server
• Secondary DNS Server
IPv6 Settings The
IPv6 configuration allows you to enable and configure IPv6 for a WAN device. These settings should be configured in combi-
nation with the IPv6 LAN settings (go to Network Settings > WiFi / Local Networks, select the LAN under Local IP Networks, and click Edit) to
achieve the desired result.
This is a dual-stacked implementation of IPv6, so IPv6 and IPv4 are used alongside each other. If you enable IPv6, the router will not allow
connections via IPv4. When IPv6 is enabled, some router features are no longer supported. These are:
• RADIUS/TACACS+ accounting for wireless clients and admin/CLI login
• IP Passthrough (not needed with IPv6)
• NAT (not needed with IPv6)
• Bounce pages
• UPnP
• Network Mobility
• DHCP Relay
• VRRP, GRE, GRE over IPSec, OSPF, NHRP
• Syslog
• SNMP over the WAN (LAN works)
