Hi @Sebastian_Herrera  
try this on input configuration file

```
input {
    udp {   
         type => "syslog" 
         port => 514 
    } 
} 

```

if you have more than one interface you can specify also the ip.

Example:

```
input {
    udp {   
         type => "syslog" 
         port => 514 
         host => "192.168.1.100"
    } 
}
```
