Currently, I am utilizing express.js for hosting an HTTP server. Is there a method available to restrict access to port 3000 through my IP address for other devices on the network?
Currently, I am utilizing express.js for hosting an HTTP server. Is there a method available to restrict access to port 3000 through my IP address for other devices on the network?
If your service on port 3000 is binding to 0.0.0.0 or 0:0:0:0:0:0:0:0, it means it can be accessed from any available address.
To limit access to only the machine where it's running, you'll need to adjust its configuration to bind solely to the localhost address - 127.0.0.1 for IPv4 and 0:0:0:0:0:0:0:1 for IPv6.
The method for making this adjustment varies depending on the particular server or service in use.
