Proxy ports
The proxy ports are the only ports that should be made available to your clients. Upstream services are accessible via the proxy interface and ports, so make sure that these values only grant the access level you require.
Your proxy will need rules added for any HTTP/HTTPS and TCP/TLS stream listeners that you configure. For example, if you want Kong Gateway to manage traffic on port 4242, your firewall must configure the Route to allow traffic on that port.
The following are the default proxy ports:
|
Port |
Protocol |
|
Description |
|---|---|---|---|
8000
|
HTTP |
proxy_listen
|
Takes incoming HTTP traffic from Consumers, and forwards it to upstream services. |
8443
|
HTTPS |
proxy_listen
|
Takes incoming HTTPS traffic from Consumers, and forwards it to upstream services. |
You can also proxy TCP/TLS streams, which is disabled by default. If you want to proxy this traffic, see stream_listen in the Kong configuration reference for more information about stream proxy listen options and how to enable it.
Admin API ports
The Admin API is used to manage Kong Gateway. You should prevent unauthorized access to these ports in production.
The following are the default ports used by the Admin API:
|
