My firewall config is below...
I am trying to figure out why another machine has access to port 5038 on my machine based on these firewall rules.
I thought the reject at the bottom would take care of all other ports? It does not.
I have restarted with "server iptables restart" and same thing. I can connect from another machine to my machine on port 5038. How do I prevent this?
