# ip rule add dev lo table Servers Solved my problem! I've spent 3 day searching for the answer. I'll make more testing tomorrow. So, correct me if I'm wrong: even if the local sending application wouldn't explicitly specify source IP address it will in any way be put to "Servers" table because it is from "lo" interface(??).
Sort of. I don't know how it works exactly, but I think that using the loopback interface as the *input* interface in a rule to match locally generated packets is a kind of hack, because it does not make much sense to me. Locally generated packets don't have an input interface.
