AWS changes the port number to name

Asked by At

AWS automatically changes the well known port numbers to name. For example 554 to rtsp.

When I am installing iptable rules, with the port number as 554, its getting changed to rtsp. This is creating problem when searching because my program passes 554 as parameter.

How to make sure that the AWS doesn't change the number to name ?

enter image description here In the picture we can see the dpt:rtsp, which actually should be dpt:554.

Perhaps you're looking for iptables --list -n? The -n prints "numeric output of addresses and ports."
