Mikrotik Crs112 8p 4s In

@enchik: Sorry, too low

@martco: Hi, I've never used the unit. I asked Ai.

What the MikroTik CRS112-8P-4S-IN is good for
Very reliable PoE switch (8 × passive PoE out)
Layer-2 switching for cameras, APs, wired devices
VLANs, trunking, link tagging
SFP uplinks are handy
Silent fanless design (great for home)
What it is not good at

The CRS112 uses a very weak CPU (QCA8511 / 400MHz class).
This means:

VPN routing is extremely slow

OpenVPN, WireGuard, IPsec → too heavy for this CPU

You’ll see only 5–20 Mbps depending on the protocol.

RouterOS on CRS switches is switch-focused

It can run RouterOS with firewall, VPN, routing, etc.
But the hardware can't push meaningful throughput.

Per-port VPN binding (policy routing) is possible… but too slow

Yes, RouterOS theoretically allows:

Assigning ports to routing tables

Policy routing based on port

Forcing certain devices → certain VPNs

But the CRS112 hardware cannot do this at usable speeds.

@martco: So, it is excellent for switching, segmentation, and PoE, but best to use it alongside a good router for VPN needs if you want per-device tunnel assignment and decent performance.

@martco: No worries, let me know if you need something different. I might have it.
