I am trying to use my BL-1300 upstream of two SonicWall routers in a failover configuration, with both on the LAN side of the BL, a fiber link on the WAN, and a cellular hotspot tethered to the USB in case the fiber goes down.
How do I set this up to work? Notes:
- Data should go to the WAN, unless it is down, and then it should fail over to the USB until the WAN is back (no balancing)
- I can’t get them to take the BL’s DHCP or respond on their WAN ports to the BL. They have a static IP on both WAN and LAN sides, with DHCP inside the LAN handled by Windows Server
- I would like to avoid double NAT
Thanks!
