Title: Multi Wan: Bonding instead of Load Balancing possible?
Post by: ThorWald on September 08, 2023, 02:38:12 PM
Hello all,

I would like to know if it is possible to bundle two WAN connections in such a way that basically there is a speed advantage. Unfortunately I have not been able to do this. Only with e.g. jDownloader it works (multiple connections) and only if you don't enable Sticky Connections (which leads to many other problems). So my question: Is this technically possible at all? If yes: Is there a how to for it?

Thanks for your answers.

You'd need an ISP who supports this via e. g. multilink PPPoE. Or set up your own multilink tunnel.

You can't simply "bundle" two independent WAN connections because they use distinct IP addresses. A single TCP/IP connection can't use two different source IP addresses simultaneously.

Cheers
Maurice

Thanks for the quick reply. I had feared that.

OTOH there are ISPs who can offer you something like that. We sure did while we were in the access/ISP business, still. But @Maurice is right, it needs a coordinated setup on both sides.

There is a proprietary technology that lets you bundle arbitrary DSL, LTE, ... lines, but it requires a central hub placed at some data centre with fast (1G/10G) and reliable uplink. You might want to look into what they have to offer:
