Uplink Balancing Standby Interface Link Down

Yes, you had it configured correctly, if the "backup" interface is set as standby. If the main active interface goes down, it will be detected and then the standby will become active. Otherwise, you can do as Bob has suggested.

FYI Matt: The Sophos mods here are not engineers and do not have in-depth technical knowledge of the UTM product. Their role is administrative for the forum Community. As with many large technology companies, most employees are not techies (management, marketing, sales, finance, etc.). Just like Astaro.org, the vast majority of the time, you receive technical assistance here from other users, which is the only realistic expectation you should have.

Thank you for the responses, I finally had some time to look at this again.  We only want the "2nd Interface" to be a backup (Backup) interface and only in use if the connection for the main (Active) interface goes down.  But when the main (Active) interface goes down, the Standby Interface is not working.  We have verified our settings under Interfaces & Routing>Interfaces>Interfaces Tab and also have verified connectivity going straight from ISP Modem to laptop set with the the same static information.  What are we missing? 

If you make the second interface active, and add the Multipath rule I suggested above, does the interface connect and move traffic if the first interface is disabled?

Is it a knownly bug(???), if you have configured a standby interface by the "native standby configuration" (WAN1 as active interface and WAN2 as standby) that the interface sometimes goes "down" shown in interfaces and will not come up; here it is a little bit stranger...I have an active-passive cluster and the interface on the slave firewall is always shown as "down" indicated on LEDs, on master it was shown as "up"...after a reboot and switch from master to slave both interfaces were down and did not come up again.

this failure I had long time before I used an active-passive cluster that the standby wan interface were gone down after few days, then I had to press the "renew ip adress" button in gui and it came up again for several days until the same error ocured again.

now I received the same error after reboot master like described below; then I tried the way to set both as active interfaces with balancing 100:0 (this should use the 0-interface (wan2 standby) only if the primary 100-interface goes down.

and to monitor both interfaces as acurate as possible I added for each one a separate host object with google public dns ip (8.8.8.8) bound on the specific wan interface.
