Hi Edward,
You will only get the bonded WAN speed for your own ISP that connected to your Balance device.
WAN load balancing (Aggregation) should work fine for your requirements. You can load balance the internet traffics using the available WANs.
No doubt SpeedFusion Bonding can help you to bond all the available WANs through your friend device (UK). You need to consider the below, before you decide the final design :
- Internet Traffics will re-route to UK, extra bandwidth requires for UK site for Internet usage.
- Upload Speed is mainly use for UK Internet to re-route internet traffics (2 x 100/20 Mbps)
For Balance model:
UK site:
Recommended: B380 (Please consider other influences before decide the model)
- 2 x 100/20Mbps + SpeedFusion
Your site:
Recommended: B210
- 1 x 13/1 + 1 x 10/0.5
Note:
2 - I’d like to backup my 16TB iTunes collection to the cloud, which is currently unfeasible
- SpeedFusion Bonding/WAN aggregation won’t help must of this (limited upload speed for WANs)
Thank You
