We have a number of WebApps that log to a graylog cluster which stands in a azure VNET. In front of this cluster we have setup a internal load BL. and successfully configured it to delegate UDP messages to the nodes in our graylog cluster. However.. we
have stumbled upon a issue with our UDP loging client and need to move from UDP to HTTP. We have tried to make the exact same setup just using TCP and the new port in the loadBL and NIC inbound rules, allthough with no luck. In our distress to make this
run we tried to setup a public (internet facing) load BL and weird enough this seems to work. However as you might understand we frown upon the idea that we have to expose our logging to the world. Might you shed any light on why it is possible for us to setup
this using a public LB but not using a internal LB?
