Hello, i am looking to harden the security on my unraid machine and i need some kind of guidance on how to do it. I will start with describing how my unraid machine is configured, I use NPM for SSL and domains redirection, the domain is local only, For remote access i use tailscale, Every docker that has a login page i am using it with strong passwords. But honestly the security feels thin, i am kinda protected from outside attacks due to accessing it only by vpn but i also use some IoT devices inside the network that for sure have crap security. Related to Unraid what can i do to have better security ? Different users for each docker if thats possible ? Certain docker programs like fail2ban, authelia etc. ( please recommend me some if there are others ) , Other stuff ? Related to the network itself, I think i should implement VLANs for the IoT devices and different wifi networks linked to those VLANs, Dedicated Firewall machine like OPNSense/Pfsense with geoblocking rules and approved only devices that can use the server ? For the network router i use mikrotik. Sorry if the post is kinda chaotic.

I have managed finally to flash IT Firmware on my Dell H310 card, so i here it is how i did it, maybe it will help someone in the future. I followed this guide: https://fohdeesha.com/docs/perc.html ( I used this one instead of the one available in this forum tailored for unraid because i didn't have access to my unraid machine at that time ) I flashed the card using my personal desktop ( R5 5500, B450 PRO4 P8 ) , be sure to disable everything that the guide mentions and enable CSM. ( PSA, with an Intel 500 platform you cannot enable CSM with out an dedicated GPU ) In my case i also needed to have every back io cable pluged in ( BT USB Dongle, Internet, Headphones jacks, Printer USB ) to be able to type a single letter into FreeDOS instead of like 30-40 at once. I do not know why this happened and sadly i didnt experiment which cable or device was allowing me to type normally so i included it all above, otherwise if only my mouse,keyboard,DP and power was plugged in i couldn't type correctly at all. After i FINALLY managed to be able to type a single letter into FreeDOS ( It took me a day to figure this stupid issue out ) i followed the guide and the card was flashed to it firmware in like 15 min.

Alright, thank you, still have not figured it out..

I am considering following this guide: https://community.spiceworks.com/how_to/188146-my-journey-into-crossflashing-a-dell-perc-h310-ir-mode-to-lsi-9211-8i-it-mode-for-zfs-truenas-use Is it any good ? Other guides recommend using two different OS's , freedos and linus, to flash the card, others dont. A lot of info around but not so much clarification about why to do it and on what hardware, server, consumer and for a begginer its hard what to trust and follow. Any help would be apreciated.

So i read a lot of info about this flashing progress and i am so confused. For now, i do not have access to my unraid machine, so i will have to do it from my Desktop ( B450 + Ryzen 5 5500 ). What would i need to do, to have an succesfull flash ? Can i do it directly from windows ? do i use freedos env from an usb ? uefi shell if my MB can do it ? The card that needs to be flashed is Dell PERC H310, i have watched the video from the art of server about the firmware and bios downloading so i think this settled.

I grabbed an Dell H310 from an local store , does anyone have an up to date tutorial about how to flash it in IT mode ?

Hello, Can anyone help with an recommendation for a good LSI HBA card ? I am located in estearn europe and my budget is around 50-60 euros. I might also use the board for a couple of ssds so i think it needs to support TRIM but i do not know if such a board is available within my budget, would lsi card from aliexpress be any good ?
