I have a RUT240 with ethernet WAN set as primary and mobile set to secondary.  The health check is to ping s3.amazonaws.com every 10 seconds, with a 3 second timeout and 5 failed attempts before failover and 3 succeeded attempts before recovery.

For some reason, the RUT240 keeps failing over to wireless, yet if I go onto CLI and I do a "ping s3.amazonaws.com -I eth1" (eth1 is the WAN interface), I get answers just fine:

root@Teltonika-RUT240:/mnt/mtdblock7# ping s3.amazonaws.com -I eth1

PING s3.amazonaws.com ( 56 data bytes

64 bytes from seq=0 ttl=236 time=6.604 ms

64 bytes from seq=1 ttl=236 time=6.669 ms

When I plug the WAN wire directly into my PC I can also ping s3.amazonaws.com fine as well.

Running firmware RUT2XX_R_00.01.13.1

Any ideas?

FYI - just tried updating firmware to latest 0.14 firmware and same experience.

Could you share with me a copy of your troubleshoot file you can share it via pm.


Hey... I really appreciate you getting back to me.

My RUT is not connected via RMS.  We are evaluating the RUT240 for potential deployment at likely over 1000 sites in the near future, but need the failover to work reliably.

Here are the latest system events from today from the WebUI when I started it up.  Let me know if you're looking for something else and how to get it.
