EoIP with load-balancing or bonding

Hi guys,
I hope you’re doing fine. I have a problem and if you can help me would be amazing. I need to interconnect my office in Sudamerica with a datacenter in Miami (USA), the connection in the Datacenter is pretty great 1Gbps. But in Sudamerica I only have access to Cable and VDSL connections. We’ve three 80Mbps/4Mbps connections here from three different ISPs (two cable and one VDSL). I would like to combine all those connection to have a 240Mbps/12Mbps connection. I imagine that the right way to do this is to create one EoIP tunnel for each connection and then add all these EoIP interfaces to a bonding interface, is that correct?

One problem I have seen is that I can’t get full speed with a single connection (I usually get only 10Mbps when I download files from the data center to my computer) but if I run multiple connections (with download accelerator o downloading multiple files) I can get 80Mbps without issues. Is there a way to run multiple session in EoIP tunnels in order to get the full speed of my internet connections?

Thanks!
