i really appreciate your help, Martin. Thank you for the great videos, they helped a lot.
Installing FusionHub on a cloud server was easy as well as connecting the Balance router.
I have 2 DSL connections 50/30 and 6/2.5 Mbit/s. A 3rd one is LTE with also 50/30 Mbit/s but this line i cannot use for telephony. If i use them together without outbound rules i get an overall speed of about 100 Mbit/s but i think that`s the normal loadbalancing, right? But if i setup an outgoing rule that sends the traffic through the vpn the bandwith reduces dramaticly. Using connection one and two should be something like 56/32 Mbit/s but i only get between 16 and 20 Mbit/s for download and 12 Mbit/s for upload. The good thing is, if i interrupt one connection, phone calls don’t get interrupted. I’ve added two pictures, the first one is the speedfusion monitor of the Balance router, the second one a localy installed speedtester (speedtester on websites show different results)
Thank you again for your help and best regards
Edit: After sending this post i found an article that discribed the problem. Bonding two lines together with such different speeds reduce the speed, because the bond will run at the speed and latency of the slowest connection
