How to tunnel a single connection through two VPN tunnels for more bandwidth and redundancy
If you have two ISP's, you can use all the bandwidth by doing per-connection round robin routing with something like this:
ip route add default scope global nexthop via ...
However, a single connection will just go via one ISP and no performance is gained.
Is there a way to split the connection's packages so half of them go through one ISP and via a VPN and the other half though the other ISP and VPN, and a server on the other side joins the pieces?
Just like ethernet-level link aggregation (teaming or bonding) but at the tcp/ip level and with VPN's added?
