I need to load balance two ISP lines that have been assigned with 1 static IP address each, but the same CIDR block, so the same gateway.
The normal load balancing settings posted various places assume the gateway is different sending a marked packet to a certain gateway. In this case, they are the same gateway, so the simple typical method doesn’t work. How should I do this?
To create two routes to the same gateway through two different interfaces, append %interface at the end of gateway IP.
