SonicWALL Failover and Load Balancing features work pretty well. Actually so well, that you may end up with one of your WAN links being down without realising it for days! To prevent this, you can setup an email alert to notify you whenever a failover event occurs.
- Go to Log > Automation
- Enter your email address in "Send Alerts to E-mail Address:" field
- In "Mail Server Settings" section enter details for your SMTP server
- Go to Log > Categories
- Select "Alerts" checkbox for "WAN Availability" category
- Select or clear other "Alert" checkboxes depending on whether you want to receive email alerts for these events
