The infamous port 32764!
-
Looks like PfSense is safe ;) but please have your friends and family check to see if their router responds to port 32764, looks like it can be a way for someone to back door your router remotely. There is a free port scanner at www.grc.com and he (Steve Gibson) has made a bitly link www.bitly.com/port32764 which will scan your WAN interface to see if you have the problem. You either want to see stealth or closed.

I assume you're talking about this?:
http://arstechnica.com/security/2014/01/backdoor-in-wireless-dsl-routers-lets-attacker-reset-router-get-admin/I don't think pfSense runs on any hardware that that backdoor runs on so we should be safe. ;)
I read that article a while ago and at the time this was an internal vulnerability only but it seems to have been updated, some routers are vulnerable internet side. ::)Steve
