It is far worse when you have multiple phones behind the same public address (i.e. NAT). If any one of the phones has a bad password and the IP gets blocked by fail2ban, then all phones at that site would be blocked.

One of the dangers with fail2ban - at least in its default configuration - is that a legitimate SIP phone with an incorrect password can quite easily send dozens of registration attempts in a couple of minutes, thus blocking that IP. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
