I have two servers. Server A is running Elasticsearch and Logstash. Server B is running filebeat and is also the server which contains all the logs I'm trying to analyse.
Server A is behind a firewall, it can reach out to the internet, but there's no possibility of allowing any inbound traffic.
Server B is in AWS and under my control for inbound and outbound traffic.
Is there any way I can get data from server B to server A's logstash? Filebeat in the usual way would have to be able to push data to logstash, but this isn't possible in my scenario.
