----------------------------------

                 Key: ASTERISK-20506
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20506
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 1.8.15.1
         Environment: CentOS release 5.8 (Final), Kernel 2.6.18-308.8.2.el5.028stab101.1, 32-bit, running on an OpenVZ VPS.
            Reporter: MBH


My Asterisk box is being brute forced and I'm getting messages in the logs referencing my box's IP instead of the attacker's:

[2012-10-03 03:49:45] NOTICE[28161]: chan_sip.c:22723 handle_request_invite: Sending fake auth rejection for device 5550000<sip:5550000 at AsteriskIP>;tag=396cbe1b

The notice message is not logging the attacker IP at all, thus cannot be blocked using fail2ban.

The same is mentioned here: http://lists.digium.com/pipermail/asterisk-users/2011-March/260377.html and here http://forums.digium.com/viewtopic.php?t=78988

I'm using type=peer, alwaysauthreject=yes, allowguest=no
