Hi,

The behaviour was not like that when I use PFsense, I raise the question as normally on PFsense was working LAN to LAN.

I check my network for LAN :
igb0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 1500

As you can see the promiscous mode is enable on lan, but on graph opnsense can't see the traffic pass from 2 devices (NAS > PC / PC < NAS) on the same network.

I ask this as to understand why and it's something where opnsense not offer?

Thank you

Any suggestion ? I try disable ids and enable no luck so far.

Ok,

I enable "Intrusion Detection"

Tick/Untick ->  Promiscuous mode
Tick/UnTick -> IPS mode

Both settings try to enable, disabled, nothing and still not showing the LAN Traffic or speed.

If I try speed test I can see 150MB on graph but if I copy from NAS to my PC no traffic or speed will show!

Thank you

Hi,

Thanks, all devices are assigned to firewall.

Wan - internet
Lan - switch 8 ports - all devices

Pfsense was showing the speed traffic as he will allocate the ip ,same with opnsense, the dhcp server on lan is set by firewall and allocated by firewall. So lan to lan as are defined by the server should be showing all traffic internal not only external.

Hi Guys,

Previous I had PFsense and but because my custom build and add on my custom 1u box a display to show CPU temp and usage and other functions on my small display 16x2 I've been forced to migrate to OPNsense.

All working fine but the only issue I found is traffic speed on LAN TO LAN. When I try to copy from my NAS to my pc the speed is not showing. I can see if someone is downloading from the internet on wan and lan but lan - lan not showing any traffic. I don't have IDS enable.

Any advice?

Thank you
