That's my routes configuration, after WAN-EPEC was my primary connection, since i added WAN-COOP it's now my primary connection, but I want it to remains WAN-EPEC as alwaysAs long as the default route uses the gateway it, you're done. Make sure is it masqueraded.
Ok, but that's no possible in dynamic connections. I kept searching in my Mikrotik router configurations and i found it !! in DHCP client exists the option.change your distance. Have the lowest number to your main connection
