SD WAN function is hot in the market these days. for Nethserver using VrayoSystems/vtrunkd (opensource package as per my info) can bring universal network link bonding and multichannel VPN capability to Nethserver.
what do you think?
AFAIK, vtrunkd is no longer developed.
I have a working sdwan prototype running on NethServer based on MLVPN (https://github.com/zehome/MLVPN).
I can publish my notes and share my configuration if you (or anybody else) want to test it.
I think that the best open sdwan setup should be based on MultiPath TCP (https://www.multipath-tcp.org/), but it can’t run in NethServer (until the mptcp patch reaches rhel kernel).
