SoftEther VPN User Forum

Is it possible to setup Softether VPN for another purpose besides securing connection? for example could we Combine Multiple Internet Connections Into One Super Fast Pipe on client side just like speedify vpn service does?
I don't mean just basic load balance bridging what I want is all my local connections available to connect to my softether connection and for them to get a single IP on the vpn server while soft ether divides the packets between all available connections I have to my local PC... Hope I managed to explain what I mean.

If this is not possible with SoftEither VPN any one know if there is an open source alternative that I can use with same exact Speedify capability?
