The cellular interface of Max-Br1 is connected to the Private APN. There is no Peplink unit at the central site and no any VPN tunnel is used.
NAT is disabled (IP forwarding enabled) on the cellular WAN interface. LAN interface of MAX-Br1 can be pinged from the central site. But, we could not success web-admin access to the LAN interface from the central or WAN side.
