Zyxel USGFLEX50 and Zyxel FWA710

jein

We run a network with Zyxel USGFLEX50 as firewall and DHCP.
Connected is a GS1900-48 switch and a Zyxel Digitalisierungsbox Basic as Internet router.

What I would like to achieve is that in case the internet router fails a 5G backup is automatically used. For this we are using a Zyxel FWA710.

I have tried several approaches, incl. static routing and policy changes but none of these is working.

What would be a fail safe appraoch to make the 5G backup work?

Our main VLAN is 1, and the Zyxel FWA710 is on VLAN 110.

Hi @jein ,

With your current devices, WAN failover (between Ethernet and Cellular) cannot be implemented due to: USG FLEX 50 does not support dual WAN functionality, and FWA710 does not have dual WAN capability. We propose two solution options:

• Replace FWA710 with FWA510: FWA510 supports WAN failover between Ethernet and Cellular.
  
• Upgrade USG FLEX 50 to USG FLEX 100 (or higher model): USG FLEX 100 supports dual WAN functionality (has OPT-WAN2 interface).

Network topology would be:
