    Disable/Enable LAN port on WAN failover

    Hi,

    I am trying to get some internet redundancy using two home ISP subscriptions, each one served through different media.

    Since there are no fancy routing protocols running, on WAN failover, I expect that all connections will need to be re-established, because the source IP has changed.

    The machines on the LAN won’t know that a failover has happened and will try to keep an invalid connection running until the apps timeout.

    I’d like to force the clients to re-establish a connection. The switch I’m using has an API I could play with. Would disabling/enabling the affected LAN ports on WAN failover be a good idea, or would it be overkill?

    Also on the Wi-Fi side, I could disable/re-enable the SSID, forcing all stations to reconnect to the AP.

      It’s been a few years but doesn’t Cisco gear have a better failover system? Call them and ask them for what gear it takes.

      To disable an interface, from Fireware Web UI:

      Select Network > Interfaces.

      The Network Interfaces page appears.
      Select the interface you want to disable. Click Edit.

      The Interface Configuration page appears.
      From the Interface Type drop-down list, select Disabled.
      Click Save.
      In the Network Interfaces page, the interface now appears as type Disabled.
      To disable an interface, from Policy Manager:

      Select Network > Configuration.
      The Network Configuration dialog box appears.
      Select the interface you want to disable. Click Configure.
      The Interface Settings dialog box appears.
      From the Interface Type drop-down list, select Disabled.
      Click OK.

      Regards,
      John
