Two routers connected to one ISP provider.

Consider a cleaner solution where the pfSense box manages two distinct LAN DHCP servers for each network and connects them via a shared WAN link. Then devices only need one switch per network, with a central switch handling both LANs. The EdgeRouter-X wizard already supports this configuration. ISP device connects to pfSense, which then routes traffic through the appropriate switches.
The PFSense box becomes a weak spot in the network, allowing regular devices to link to the ISP device while the PFSense box itself stops functioning.
Yes, these terms refer to different network configurations. Cascading handles traffic flow across multiple links, bridging connects segments within a network, and IP passthrough allows specific traffic to bypass routing. This is the right approach for your setup. Spoiler: Choose the right one based on your topology!
It mostly depends on the specific ISP router model. Usually it indicates that all ports are sent to another device on the network, often referred to as the next router.
