2 adsl different ip same gateway how to

how can I use at same time two adsl lines that have two fixed ip address
they are connected in pppoe
when connected they receive the ip dynamically (but is always the same)
system adds two dynamic routes destination 192.168.1.100/32 (dslam) one with preferred source the public ip of the first pppoe interface the other with preferred source ip of the second pppoe interfce and I have two routes to 0.0.0.0/0 to 192.168.1.100

mikrotik marks as active just one of the two routes hence packets going in from both lines but going out just from one

any suggestion

use ROS v3 with interface routing

use ROS v3 with interface routing

I did that but still isn’t working.. the problem is that the connected routes installed when the interface is brought up by the pppoe client are the same.

but interfaces are different, so set gateway interface in routes
