Cannot Forward Port

I have set allow 1/65535 TCP in the Securtiy Group Rules settings.
However, the ports are still blocked. No any port can be connected.

About the method to set rules, please check the link below:

Also, you should check the rule of iptables in your system.

If you still can't solve your issue, please create a ticket with your instance ID.
