[AsteriskBrasil] Capture estranho !!!

[LUIS CARLOS FIDALGO]

Boa tarde galera,

Coloquei um asterisk  para á internet hoje ja configurado com o Fail2ban e
funcionando perfeitamente, pois ele bloqueou automaticamente esse ip abaixo,
conforme abaixo;

 

Chain f2b-ASTERISK (1 references)

pkts bytes target     prot opt in     out     source
destination

22 13332 REJECT     all  --  *      *       187.255.102.6        0.0.0.0/0
reject-with icmp-port-unreachable

1956  143K RETURN     all  --  *      *       0.0.0.0/0            0.0.0.0/0

 

Mas ainda continua sem parar subir no log que está chegando na eth0

Algo para me preocupar ou não?

 

# tshark -R sip -i any

 

Capturing on 'any'
