Ok here is a question I've not had before. I'm trying to set up a linkpoint api for a customer's ecommerce site and they need port 1139 open for incoming and outbound traffic (confirmed with linkpoint). I've always left the standard setup run as leased and just verified that the appropriate ports are blocked. How do I open just this port in Redhat 7.3? I figured I'd check with the experts so I don't leave something unintended open. My server provider has not been helpful with this. Thanks!
