Model: ER707-M2  
Hardware Version: V1
Firmware Version: 20260325 Rel.78146

ER707-M2 v1.20 running 1.4.1 Build 20260325 Rel.78146

Local management. No Controller.

 

Load Balance - On.

tried Lower weight on Wan1 and Higher on WAN/LAN2 (reversed, same result)

tried Enable Application Optimized Routing

 

It DOES FO and Failback. but then settles on WAN2 always. (Wan2 is my slower backup connection,. I need to "Use First Primary WAN1" unless its down.

  @Tarkin 

The issue was totally unrelated to the 707.

The PC I was testing with had a dual NIC :( 

So the PC was picking which WAN to go out of.

 

707 works fine by default WAN Failover!

great device

  @Tarkin In standalone mode, Always Failover mode is the default, and you cannot change the setting. This may be an issue with Online Detection for WAN1; can you make sure the uplinks are working fine? Also, check if there are any logs showing the WAN came back up.

Hi  @Tarkin 

 

Thanks for posting here.

Does the issue persist?

 

When link backup is enabled, the following config will not take effect. You may disable them

Load Balance - On.

tried Lower weight on Wan1 and Higher on WAN/LAN2 (reversed, same result)

tried Enable Application Optimized Routing
