Hello,
Please avoid bumping up your post, there is no SLA on the forum and not even 24 hours has passed from your question.
This is unrelated to Logstash, as I said on your previous question this is a network/infrastructure issue. you need to check with some openshift community.
If you can connect from outside your openshift cluster to the Logstash port, than you probably can send data to Logstash.
Not sure what you mean with this.
The screenshot you shared shows that Logstash were able to receive data and send it to Elasticsearch, if you syslog still can't send data you need to troubleshoot it, maybe you have some connectivity issue between the syslog and logstash.
Do you have any errors/warn logs in Logstash log? If you have, please share it.
