enable MPTCP protocol
Networking support->Networking options->TCP/IP networking->MPTCP protocol (MPTCP)
use the Linked Increase Algorithm (LIA) Congestion Control, that guarantees fairness across a shared bottleneck
Networking support->Networking options->TCP: advanced congestion control->MPTCP Linked Increase
To enable it as the default congestion control, you should also enable it in "Default TCP congestion control", or you just type echo 'lia' > /proc/sys/net/ipv4/tcp_congestion_control in the running Kernel. Other options are "Opportunistic Linked Increase
(olia)", "WVEGAS CONGESTION CONTROL (wvegas)" or "BALIA CONGESTION CONTROL (balia)".
Choose a path-manager, by enabling "MPTCP: advanced path-manager control"
enable Policy-Routing
Networking support->Networking options->IP: advanced router->IP: policy routing (IP_MULTIPLE_TABLES)
