Problem:

 

I have a problem with the Load Balancing on my ER7206. My primary ISP is FREE.FR with Freebox Rev (Router mode); my backup ISP is my MR6400 with a LTE 4G connection. My primary link is breakdown for 3 days. My Freebox is alive but no Internet connection. The ER7206 don’t swap on the backup link automatically. I must unplugged the primary cable to force the backup link on 4G. Then, i have Internet connection. No problem with that. But when i plugged again the primary cable, the backup link is balancing on primary connection. But the primary ISP don’t working… I don’t understand, the ER7206 don’t check an URL or a DNS to validate the connection. It looks like the primary connection is always alive when the cable is plugged.

 

What is my problem in my configuration ; i have missed something ?

Thanks for your help.

Best regards
