3. PfBlocker disabled pf when router was booted with no internet

PfBlocker disabled pf when router was booted with no internet

  • T

    Hello,

    I just had a router reboot and there was temporarily no internet when it came back up.  No traffic would pass from behind the router then, and it appears that pfBlocker errored out and disabled pf (below).  This is an Alix 2d13 running pfSense 2.0.1 and pfBlocker 1.0.2.

    This router also seems to have squid binaries installed, even though squid isn't shown in the GUI as an installed package, so I think I need to zero out the flash card, reload, and import the config in fresh.

    Is the pf problem related to the squid issue, or is it a lingering problem mentioned in this link below?

    This happened again, and on a different router - running 2.0.1, pfblocker 1.0.2 on an Alix board:

    Has anyone else experienced this?

    yes, the reboots take much longer with pfBlocker, as per the link described.

    But it shouldn't disable pf all together, don't see that it actually does in this case?

    Yes, I've had this happen on two occasions.

    Both times the router lost power the night before and the users had no internet access when they came in in the morning.  Disabling pfblocker restored their internet access.

    I have not been able to reproduce this so far on a test router.

    Maybe you should report this to marcelloc in http://forum.pfsense.org/index.php/topic,42543.0.html? It's probably related to the pfBlocker taking longer to boot up on embedded problem.

    Ok.

    To convert a regular computer into a testing router, how do you install the embedded pfSense image, do you just dd the image onto the hard drive?

    I use VirtualBox myself:

    I was able to reproduce this on a test router, and I have posted this at:
