A customer was using our application, which, by default, uses three specified TCP ports, 9898, 8080, and 1169.
This customer did not want to use our stock port numbers for security reasons. That is just fine, our product supports using alternate ports for all three. Unfortunately, this customer selected TCP ports 1, 2, and 3.
These ports are "reserved" by the IANA for other uses, and this choice was causing network instability in their environment. After more than a year of support calls, the customer changed the ports, but didn’t want to use the stock ports. He asked if he could just put “50” on the beginning of each stock port number, which, of course, is far too long.
