1gbs router on a 2.5gbs network?

You keep saying your avoiding port bottle necks, but there wouldn't be one with everything connected to a LAN port anyway everything would still get switched through the switch, that's the whole point of them.

For anyone still doubting:

• Openreach’s own wiring guide shows the ONT’s Ethernet can be extended through internal Cat6/patching before it reaches the router. That’s literally an L2 path (the same thing a switch provides).

• BT Business FTTP setup confirms the router terminates PPPoE on the WAN, so the router remains the L3 boundary. Anything between ONT and router is still just L2 transport.

• EE Smart WiFi documentation shows the satellites use Ethernet backhaul in bridge/AP mode – meaning they do not route or NAT.

In my setup:

• The router holds the public IP and runs PPPoE.
• All clients get 192.168.1.x from the router’s DHCP.
• NAT Type 2 on PS5.
• Firewall is still active.

That only happens when WAN and LAN are logically separate and the router is still the L3 boundary.

This completely dismantles the idea that “a switch before the router collapses or bypasses the boundary” – the behaviour of the network itself proves the separation is intact.

That was my original intention when I misunderstood the ports on the router and satellites. However, now that I have had this corrected, I still won’t be changing back because the network improved when I made the change and, as demonstrated, it’s an entirely valid thing to do.

The hyperbole I was faced with on this was absurd.

All someone would need is an ipv6 address and your completely unprotected. But you know best.

I'm not going to waste any more time on this thread, but it's comments like this which demonstrate that you really don't understand as much as you think you do. Extending the ONT by using internal wiring is not a layer 2 path at all, it's layer 1 (physical), and it is not the same thing that a switch does.
