Netstat show's the listeners on 5002 and 5044 for syslog and file beats:

[root@node1 logstash]# netstat -tauplan | grep 5002
tcp6       0      0 :::5002                 :::*                    LISTEN      11288/java

[root@node1 logstash]#

TCPDUMP shows the Syslog data hitting the interface without issue:

However no data is showing up in Elastic and when I do quries for SYSLOG there's nothing there.
