3.On pfsense I got stuck here where I really can't bond them. Stick connections was an issue also building it on a wm was not a great choice https://www.netgate.com/resources/videos/multi-wan-on-pfsense-23.html
MultiWAN : Loadbalancing TCP connections over several lines. Each stream is limited by the 50/10 MBit/s of your connection.
Wanna go for it. Don't know if it is worth doing it
MPTCP-VPS : One TCP connection is split into peaces and transmitted via multiple DSL-Lines to a virtual private server (VPS) and combined there. However, you can say that your bandwidth of the tcp connection is approx the combination of your DSL-Connections.
OpenMPTCProuter is a great software based on OpenWrt and MPTCP kernel.
But the support is limited to a number of devices only.
I used openmptcprouter for months before moving to my customized builds. For my usage, openmptcprouter was heavily bloated which caused the device to reboot frequently.
I am currently using a fork of openwrt with mptcp along with MPTCP enabled kernel in a VPS hosted in DigitalOcean.
I have installed on a virtualbox but could not access it. Even thoug i have host-only network adapter attached. The main page does not load on 192.168.200.1 which i have updated from 100 to 200.
