HI there!
For the failover purpose now i’m using Netwatch tool and it works great!
My first ISP is local wired provider and the second is the USB 4G modem with Hilink firmware.
But the problem is that my wired ISP uses some like a proxy or a billing system. And when my paid period ended, Netwatch tool still shows “Up” status.
ICPM replies, DNS and even Fetch tool works (http protocol) , but i can’t open any URL.
Also i have the OpenVPN connection with my office network, but i don’t want to use in tests.
I need any script or another solution that i can use in different places, not only in my home LAN.
Thanks for any help!)
