Hi ,

I recently made a post about my Firewall Mini PC specs. I mistakenly wrote that the CPU is an Intel N150, but the correct CPU is actually an Intel i3‑N300.

Here are the correct specifications:

    CPU: Intel i3‑N300

    Ports: 2x 10G SFP+ and 3x 2.5G (i226‑V)

    RAM: DDR5

    Storage: NVMe

    OS: OPNsense (latest)

My apologies for the confusion. The rest of the details about the 10GBASE‑T SFP+ modules and compatibility remain the same.

Thank you to everyone who responded, and I appreciate your understanding.

Hi everyone,

I've been researching a direct 10G connection between a Firewall Mini PC (with 2x 10G SFP+ ports) and an Intel X520-DA2 NIC installed in a separate server. Both sides use the same network chipset and driver.

Here's a quick compatibility summary based on my findings:

Item   Details
Chip on Firewall (built‑in SFP+)   Intel 82599ES
Chip on X520-DA2   Intel 82599ES
Driver (both ends)   ixgbe
DAC cable compatibility   ✅ Excellent – same chipset, passive DAC works natively
OPNsense support   ✅ Native support (ix driver / iflib)
Key takeaways:

Both endpoints use identical 82599ES controllers, so a direct passive SFP+ DAC cable works without protocol mismatches.

OPNsense supports these interfaces out of the box. If you use third‑party SFP+ modules, add the tunable:
hw.ix.unsupported_sfp = 1

No extra configuration is needed for a DAC cable straight between these two devices.

Hope this helps anyone building a similar 10G backbone between a firewall appliance and a server.

Feel free to share your own experiences or ask questions.

Thank you, friends, for expressing your opinions.

Hi everyone,

I recently got a Firewall Mini PC with the following specs:
- CPU: Intel N150
- Ports: 2x 10G SFP+ and 3x 2.5G (i226-V)
- RAM: DDR5
- Storage: NVMe
- OS: OPNsense (latest)

I'm looking to use the 10G SFP+ ports with a 10GBASE-T RJ45 Copper module instead of fiber or DAC, since I need to connect to standard Cat6a ethernet.

I know the official OPNsense compatibility list only covers their own hardware (axgbe-based appliances), and my device uses a different SFP+ controller.

Has anyone used a 10GBASE-T RJ45 SFP+ copper transceiver on a similar Mini PC setup running OPNsense?

Specifically I'd love to know:
1. Which module did you use? (brand/model)
2. Did it work out of the box or did it require any configuration?
3. Any issues with heat since the device is fanless?

Thanks in advance!

Hi

I Can't download/update apps from Google Playstore with opnsense

pls help

Hi

I encountered a problem when using opnsense, and it is that I cannot open the Google Play Store in the mobile phone, and it appears

bending

Please Help

my regards

Hi
I have a firetvstick device and it was working for me normally, except after I installed opnsense, it did not work. There is an IP from the network, but there is no internet
I can ping  firetvstick from my pc

Is there a setting I can make that works for me?

Thank you for your help

Thank you for your help, but I have a Raspberry and I installed opnsense on it and I only have one network adapter and I have a USB network adapter type AX88179
USB3.0 to 10/100/1000M Gigabit Ethernet, but the problem is that it is slow in speed

Is there a way to use the internal network adapter to be to the two wan and lan

Can I make trunk port

my regards

Hi

What is the command to install USB to Ethernet Adapter for opnsense

Hi

install opnense VM in synology nas But I encountered a problem with the bridge mode. It Giving WLAN as 0.0.0.0_8 for address in Bridge Mode

But I tried it from bridge mode to normal mode, it takes a number from the network 192.168.5.150.

Is there a solution to this problem


my regards

Hi

4.2 Modify config.txt (RPI only)
The config.txt in the first partition needs to be modified depending on the RPI model you get. There are also config_rpi*.txt files for your reference.

Additionally, you can add the following lines in config.txt to enable serial console:

1
2
3
# Fix mini UART input frequency, and setup/enable up the UART.
uart_2ndstage=1
enable_uart=1

Can you explain to me how to use these files, should I modify them, rename them, or what? Please help
