Scenario… would really appreciate some practical input/comments…
6 x Fusionhub Solo on separate VLANS - common WAN IP - 100MBit fibre connection
- 6 × Balance 20, each with Speedfusion Alliance pack, and WAN3 Activations.
- Each has vdsl internet service with ISP ‘A’ on WAN1 of Balance20, modem in bridge mode
- Each has vdsl internet service with ISP ‘B’ on WAN2 of Balance20, modem in bridge mode
- Each has 4G/LTE internet service with ISP ‘C’ on WAN3 of Balance 20, 4G modem in bridge mode and services have public IP (not NAT)
Each of the Speedfusion tunnels are set as point-to-point tunnels from client to Datacentre.
Client 1 has speedfusion tunnel to fusionhub 1, data port set unique to 43013
Client 2 has speedfusion tunnel to fusionhub 2, data port set unique to 25015
Client 3 has speedfusion tunnel to fusionhub 3, data port set unique to 10015
All tunnels hook up fine, all routing working perfectly, voip and RDP for each client working nicely. No issue.
But… if ONE of the client internet links goes down (say) at client 1, their whole speedfusion tunnel drops, renegotiates based on now just 2 of the 3 links being available, then speedfusion comes back up. This might take a minute. Later, when the faulted internet link returns online, again speedfusion drops for that client for minute, renegotiated speedfusion tunnel based on 3xlinks… tunnel back online.
In speedfusion config (using incontrol2), forward error control set to low, wan smoothing at medium, WAN1 & WAN2 set as priority-1, 4G set as priority 4, Link failure detection time - have experimented with various… currently set to ‘Extreme’.
Obviously, the whole goal here is unbreakable VPN by bonding 3x internet services per client… but the speedfusion tunnels are breaking every time just one of the links fail… and thus lost voice calls and dropped RDP sessions. The recovery time of these tunnels is a minute (compared to under 4s when ipsec was used).
These are not large client sites… typically 10x SIP handsets and 10x RDP clients… so throughput is low (typically less than 4MBps)
Any ideas??? Or is it simply that Ive misunderstood, and Speedfusion will not work to maintain an uninterrupted speedfusion tunnel without drop despite a single link failure? Config error? Incorrect expectations or shortfall of the alliance pack?
Edit: All on v8.01 firmware.
Thanks for reading, and input valued.
PS: Is there a ‘speedfusion tunnel availability’ report available, where I might be able to demonstrate tunnel availability versus individual link availability? I.e be able to show clients (graphically) how much better life really is with Speedfusion?
