Configure Sonic Wall TZ 190 for 2nd WAN connection and fail-overfrom the primary.

I would like to configure our Sonic Wall TZ 190  (running SonicOS Enhanced 4.0.3.4-12e) to add a WAN port for a second internet connection, and setup failover with notification and logging that will switch to the backup service when the primary fails, then fall back when the primary is restored.

We currently have 4 of the 8 LAN ports on LAN, and 4 on a PortShield Interface 1.

I need to:
Configure one of the LAN ports as a secondary WAN source;
Setup fail over and fall back so that when the primary fails, traffic is routed to the secondary; and when the primary is restored, traffic is routed to the primary.
Hopefully without interrupting service, but if it is required, I can arrange that.

Thanks, Harold

Dear,

"Configure one of the LAN ports as a secondary WAN source" This is not possible as on Tz-190 you will have optional port, please use that port as WAN

"Setup fail over and fall back so that when the primary fails, traffic is routed to the secondary; and when the primary is restored, traffic is routed to the primary"

"Hopefully without interrupting service, but if it is required, I can arrange that" No restart required.

Sorry for the delay, your reference was very informative and I was able to configure the OPT port as the secondary WAN interface.
