Yes I looked into doing that too!
I tried with a Netgear GS110TP switch which has two SFP ports connected directly to the firewall and it works well. (But I would like the TV not to go through the firewall)
SO I told myself that I was going to install a new router…but finding one that supports my gigabyte connection is a hassle! There is the Ubiquiti Edge Router Lite which supports 1 million packets per second thanks to its hardware acceleration but as soon as you bridge two ports this deactivates the acceleration and in any case it does not do passthrough.
Then there is MikroTik-RB2011UIAS-2HND-IN which has a direct SFP port but the performance is poor…
in short, the purpose of this story is that it makes us buy gear while all they have to do is activate this option! (which, I repeat, was available BEFORE!)
