I‘ve two network interfaces. One connected to eth0 and another connected to eth1 as follows:


eth0 => private network with private IP in 10.x.x.x/8 range.
eth1 => ISP router with public IP 205.153.203.98 via 205.153.203.97.

How do I setup persistent static route so that 10.0.0.0/255.0.0.0 traffic route via 10.70.201.61 router only?
