Hey there, totally new to the Forum, i am very pleased with my RB4011, but since it ist my main Internet Gateway it does not suit very well for experimentation.
I am dreaming of a very simple device. 2 Gbit Ports, POE in / Out, GHz class quadcore arm, 256Gb RAM, 512 NAND, full Metal cast housing.
Especially for docker / PPPoE Client, Wiregard endpoint, Scripting Lab.
One can dream, right?
Rather pointless with only two interfaces with all that performance?
I don’t think that Router exist at the moment !
But keep on dreaming =)
The new RB5009UG+S+IN is very focused on Lab enviroment
And as a lot of the features you are looking for.
Alternatively,
All my colleagues at work use a Mikrotik hEX S
It’s a very nice Router to learn and experiment with for around 60$
I personally am on the road a lot,
So I needed a nice Travel and network Diagnostic-Router
With Features like:
→ PoE-In and PoE-Out
→ Wifi 2.4 and 5GHz
→ Bandwith-test, Monitoring-Tools…
→ VPN’s and more
I endet up using a Mikrotik CAPac
Designed and 3D-Printed a new housing for it
It’s not perfekt, but quite a nice Solution for my problem !
So NanoPi R4s with PoE In/Out and ROS onboard? 
Is possible to install RouterOS x86_64 inside,
netinstall MkroSD with windows / linux and put inside the bay.
Probably also CHR because “probably” support also ESXi or similar…
I hope one day update that with also 5GHz,
Thanks for all the feedback,
especially to XVO, i did not know about the NanoPi R4S. Now i want one!
