OpenMPTCProuter is an open source solution to aggregate and encrypt multiple internet connections and terminates it over any VPS which make clients benefit security, reliability, net neutrality, as well as dedicated public IP.
The aggregation is based on Multipath TCP (MPTCP), which is ISP, WAN type, and latency independent “whether it was Fiber, VDSL, SHDSL, ADSL or even 4G”, different scenarios can be configured to have either aggregation or failover based on MPTCP.
