I am trying to run a java application on my EC2 instance. The application accepts socket connections on port 54321. If I try and connect to it, it times out. My Security Group is set as:
TCP Port (Service) Source Action
21 0.0.0.0/0 Delete
22 (SSH) 0.0.0.0/0 Delete
80 (HTTP) 0.0.0.0/0 Delete
20393 0.0.0.0/0 Delete
54321 0.0.0.0/0 Delete
Is there anything else I need to do?
# iptables -nvL
