Hello @jruiz,
You may have already checked though it is worth another look at your connections between your Peplink/MAX routers and the outward bound network connections that they are not blocking the required Port#s, this includes checking with your ISP/Carrier, many ISPs/Carriers block higher level ports now in an attempt reduce the usage of P2P transfers (such as bit torrent transfers).
Also we highly recomed that you upgrade the Peplink/MAX devices to the latest firmware also.
In addition please let us know if you are using InControl2 to build & manage your SpeedFusion or settiing it up directly on your devices, we recommend building SpeedFusion using InControl2 over doing it directly within the devices especially for first timers
See how you go with this and let us know.
Happy to Help,
Marcus
