Allow HTTP to non-standard port
This is probably a super basic question but I have not managed to figure it out.
I need to allow users to access HTTP on port 9000 at a particular external IP address. Currently they seem blocked by the firewall. I've tried adding a custom http proxy with that port for all external addresses but something is not right as the firewall still blocks it.
Would anyone be able to provide a quick step-by-step of how to do this?
Many thanks in advance
