I am trying to set up a BR1 MAX Mini. I am going to put the BR1 between the modem and the VOIP switch. I need to make sure the BR1 is in IP passthrough and no routing/DHCP is made from the BR1. If I set “IP Passthrough”, will I still have access to the client to be able to manage the BR1? It will need to provide Passthrough of WAN IP and 4G IP.
