Hi,
I get a lot of these messages on my Asterisk CLI:
"Failed to authenticate user
1000<sip:1000@MY_OWN_IP_ADDRESS>;tag=03f82bb9"
as if my PBX machine is trying to authenticate to itself. It seems
someone is attacking my asterisk PBX.
Is there a way to fix this problem?
in sip.conf I have guest connections permitted and have them going to
the default context which contains :-
[default]
; all unauthenticated connection attempts from the internet come in here.
exten => _[+*#0-9].,1,NoOp(Unauthenticated call attempt -
${SIP_HEADER(Contact)})
exten => _[+*#0-9].,n,Congestion
Then in fail2ban I have it match the following :-
failregex = Registration from .* failed for \'<HOST>\' - Wrong password
Unauthenticated call attempt .*\@<HOST>\:
