Okay... I will do it without opnsense and directly on Unraid.

Thx sphbecker

Hi,

I'm running opnsense on VM (Unraid/QEMU) and want to use the network interfaces as a switch.

While there is a good documentation for a non vm version, it seems not to work running inside a vm (I double-checked the docs).

Let me give some details.

---
VM
---

Physical Interfaces:
4x RealtekCo. RTL8125 2.5GbE Controller

Virtual Interfaces:
2x virtio-net / br0

-----------
opnsense
-----------

Interfaces:
- LAN (lan) ---> bridge0 (Bridge)
- Mainboard (opt2) ---> vtnet0
- OPT1 (opt1) ---> re3
- OPT2 (opt3) ---> re2   
- OPT3 (opt4) ---> re2
- OPT4 (opt5) ---> re1
- WAN (wan) --> vtnet1

WAN (wan) has a IP from DHCP server which runs on my router. So WAN is just bridged with my real LAN. I use the WAN to access the opnsense.

LAN (lan) is the opnsense bridge0 with assigned Mainboard, OPT1, OPT2, OPT3, OPT4 device an local link is off.

------------------------------------------
So the goal is, to build a switch 4 physical and 1 virtual nic. I want to attach my notebook to one phyical interfaces and it should be conncted to my original LAN automatically.

Unfortunatelly it doesn't work. I have no clue and need some help.
With "systat -ifstat" I just see "in" traffic for bridge0, but no "out" traffic.

Does somebody has a idea what I'm doing wrong?

Thx for any help.
