I see it has been asked many times, but I couldn't find a final answer. I used Pihole until now, but I would give Diversion a try. Have a Sandisk Ultrafit USB 3.1 32GB. The router is Ac66u B1 running latest Merlin.
Maybe even add Skynet.
1) I guess I should use the USB 2 port and not the USB 3, correct?
2) I will format the usb drive with the script on router, but: ext2, ext3 or ext4? I see many suggest ext2, but also lot of posts about ext4. So what is the way to go?
3) what is the recommended swap file size? Diversion with pixel and biggest list + maybe Skynet.
