General Discussion / Setting up an IOT LAN

« on: December 08, 2019, 08:17:04 pm »

Hi,

I'm a long-time OPNsense user and am contemplating the best way to set up a separate IOT LAN.

My OPNsense PC has a dual-NIC motherboard. I'd like to add a PCIe NIC and have all my IOT devices sit on this NIC/LAN.

I think I'll set up a separate class C address space for this LAN. I think I should be able to create rules to allow devices on the normal LAN to be able to reach the IOT LAN, but not the other way around. Does that sound doable?

I'd appreciate hearing any thoughts or advice you might have.

Thanks,
John

Hardware and Performance / Support for Intel Wireless-AC 9560

« on: December 07, 2019, 07:25:43 pm »

Hi,

My OPNsense firewall is based on an ASUS ROG Strix H370-I.

This board includes an Intel Wireless-AC 9560 [Jefferson Peak].

I'd like to use this wireless interface to set up an IoT wireless LAN to move all my IoT devices off my primary LAN.

Is it possible to make this wireless interface work with OPNsense? I had hoped by picking a popular, main-stream motherboard that hardware support would be fairly decent.

General Discussion / How do I analyze traffic?

« on: July 14, 2019, 03:50:30 am »

Hi,

Thanks so much for OPNsense. It's wonderful to have such a powerful solution.

How do I analyze the traffic on my network?

I have IOT devices and I wonder what they are doing. Are they connecting outside my network? What ports are they using?

How do the pro's use OPNsense to figure this out?

I have OPNsense running on a very beefy dedicated PC with plenty of storage. Do I do a packet capture and then analyze the data? Is there a way to capture netflow data and then review it with some sort of purpose-built GUI?

Thanks,
John

19.1 Legacy Series / Kernel trap 12 after upgrading from 18.7 to 19.1

« on: March 02, 2019, 01:28:40 pm »

Hi,

My OPNsense box has been running great for many months. I decided to upgrade from 18.7 to 19.1 today and now my system won't boot.

I downloaded the latest 19.1 image, burned it to a USB drive, and when booting from it, I get the same error.

My hardware is ~6 months old. I built the system specifically to run OPNsense. Do you have any idea what might be wrong?

Thanks,

18.7 Legacy Series / TiVo Streaming not working through NAT firewall

« on: December 23, 2018, 02:20:28 am »

Hi,

I'm running OPNsense 18.7.9-amd64 and having a really fun time analyzing traffic on my network.

I've noticed that my phone and tablet are no longer able to stream TV from my TiVo using the TiVo Android app. I can browse channels and see the recorded shows, but when I try and stream a show, it fails.

Do you have any idea what setting in OPNsense might be causing this? Streaming works fine on my Netgear firewall. I suspect there is a setting in OPNsense that I've not set correctly.

Thanks!
John

Hardware and Performance / Does OPNsense support Intel RAID M.2 SSD's?

« on: November 21, 2018, 02:52:57 am »

Hi,

I'm building an ITX PC to run OPNsense. I would like to install dual M.2 SSD's and RAID 1 (mirror) them so that if one fails my OPNsense firewall will continue to work.

Is installing on a RAIDed SSD supported?

Here is the HW I'm planning to use. I welcome any advice on it.

John
