I'm having issues with recursive routing failover setting. When an ISP fails the router stops to receive a pong and sets next routes with highest cost as active. That's alright.
The problem is that when there is a failure in an ISP, all devices in LAN can access to some web sites, but they can't access to some other web sites.
That's i think because connections still established by the fallen WAN. I need to modify connection-tracking settings to solve this problem but i don't know what values should i modify.
Thanks for all,
