Routes depend on the *destination* address only. Source address has no effect on which routing table entry is used for a certain packet. If you require traffic with a certain source address to be sent via a certain interface, that is not a job for the classic routing table, you will need to use another method involving PF for route selection (either route-to / reply-to, or you may be able to do this with multiple route tables). > Do you have any explanation for this routing inversion > or a workaround/good practice to have a ping -I always working as intended? This is working as intended..
