Dear Bernd, thanks for your helpful responde....but now I have a new 
question.

I have a Graylog2 server with just one INPUT "Syslog UDP" listening on port 
UDP/10514, and the tutorial said I have to create another INPUT "Raw" 
suppose listening on port UDP/5555.

How can I connect the raw input with the syslog input ??? I got lost...

Thanks in advance,

Roberto
