MTU and IP Passthrough

Network topology:
MAX BR1 Mini (IP Passthrough) > Balance One > LAN

  1. Should MTU be configured on Balance One to match that of MAX BR1?

Or, is the BR1 still handling that handshake, meaning the MTU for Ethernet link between BR1 and Balance should be left at default?

I would leave the Balance One WAN at default.

Let the BR1 manage it.
