So recently while trouble shooting that mail log in problem from my phone, I started going through the web interface on my pfSense box. While in the LAN interface, and it being 4am, I was like why is block RFC1918 for the Wan (which is on every interface tab), and block Bogons, not checked.
So I did what anyone half sleep deprived would do, I checked the boxes and hit apply. Then I couldn’t get back in to the silly thing. Console wouldn’t work. I just got a blank screen, rebooting while consoled in would go through the post and loading of BSD but after pfSense started, I didn’t get a menu.
Hey I know, I’m a Nix person, I’ll boot from the live image, go in to recovery find and turn off that setting, sync to the hard drive and reboot.
