Hello. OpenVPN newbie here.

Got two ISP's. Trying to take advantage of both ISP's simultaneously for more bandwidth. Standard routing can do this with something like this:

ip route add default scope global nexthop via ...

However, this way a single connection will just go via one ISP and no performance is gained. Only multiple TCP connections and/or UDP would improve performance, and I'm not sure about UDP.

Does OpenVPN provide a good way to split a connection's packets so half of them go via one ISP and the other half go via the other ISP, and a server on the other side joins the pieces?

Would the OpenVPN server need any special setup to make this work? Is there a way to do it that works with most OpenVPN servers publically available?
