Question

Hello

I have a RUTX11 with Primary WAN interface provided by Ethernet, and SIM1 is a 4G failover. I need some clarification on the correct setting for "Flush connections on" in Interface configuration. The options are "none", "connected", and/or "disconnected". 

It is very unclear to me what these mean. Is it referring to the interface itself being connected? (e.g. when mob1s1a1 establishes a link?) or when any interface gets connected? What is the best practice here?

Here is the behavior I want, can you please tell me how to configure this:

• WAN1 (Ethernet) should be used at all times - NEVER use SIM1 if WAN1 is online
• IF wan1 goes offline, ONLY THEN use SIM1
• flush states on WAN1 when it transitions from WAN1 -> 4G / SIM1
• as soon as WAN1 comes back online, flush states on 4G/SIM1 to force connections back to WAN1

Thank you

Hello, 

Here you can find more information about the Failover configuration. 

https://wiki.teltonika-networks.com/view/RUTX11_Failover

To achieve the configuration you want you must configure in the Failover the WAN network as Flush connections on Connected. So when the WAN fails it will go to the mobile network because of your failover configuration, and when the WAN comes back online it will redirect all connections to the WAN again.

Ok thank you, so to confirm, I should set Primary (WAN) to flush on CONNECTED. And leave the Secondary (4G backup) to BLANK?

Yes, correct.
