Hi,

Don't keep that old version, get a most recent version 2.3.2

2.3.2-RELEASE-p1 (amd64)
built on Tue Sep 27 12:13:07 CDT 2016
FreeBSD 10.3-RELEASE-p9

pfSense can not be 'hacked'.
Said otherwise : you have a 0,000001 % chance that the guy takes down your system and a 99,99999 % chance that your 'setup' is … well .. how to say it : "not Ok".
