This is somewhat related to - but different from - Recommendation for a non-standard SSL port .



One answer there suggests that binding to 8443 is a valid example of an alternate HTTPS socket configuration. However, under some Windows systems, 8443 falls within the ephemeral port range.



My questions are:



  • Are there any risks associated with binding a service - such as sshd or httpd - to listen to a port in the ephemeral range?

  • Could it interfere with the creation of outgoing sockets? In particular, will a listening socket and a connecting socket on the same address with the same port interfere, collide, or otherwise fail?

  • Is it expected in such a case that a client request a new ephemeral port until it finds one that is available?

  • Other than all mentioned products being EOL, i suppose there shouldn't be a problem. Or just reconfigure the EPR on the systems. (or use modern OS/software, which ususally has an EPR of 49152 to 65535)
