WARNING! DO NOT USE snapshots built between June 3 and June 8

[gnhb]

Snapshots from June 3 to June 8 have a problem that can cause strange problems and behaviors with routing.
(pfSense does not recognize the last interface in the interface list given by the OS as being a valid interface.)

Please use snapshots from June 9th or later.

Thanks,

GB

There are also issues with SSL in various places in those snapshots as well. June 10 snapshots should be OK.

If you want to fix this issue without downloading a new snapshot, it's a one liner.
if you're on a nano install, you must make the file system writeable first with

#/etc/rc.conf_mount_rw
