Explanation

A firewall's primary role is to act as a security boundary between an untrusted network (the Internet) and a trusted one (the internal LAN). Placing it between the broadband/Internet connection and the local network means all inbound and outbound traffic must pass through it, giving the firewall full visibility and control. Placing it inside the local network leaves the network edge unprotected. Placing it 'between the broadband connection and the Internet' or 'in the Internet cloud' is nonsensical - the organization does not control those segments.
