One thing I forgot to mention: set the “frontend URL” in the master realm to the admin URL (Note: you need the scheme here like http(s)://〜). Reference: [frontendUrl and adminUrl - how to restrict admin console to internal IP only?](http://forum.keycloak.org/t/frontendurl-and-adminurl-how-to-restrict-admin-console-to-internal-ip-only/2655) However, changing the port number require a slightly tricky configuration. if you want to use localhost:8080 and localhost:8081, start with the following command, then add “[http://localhost:8081](http://localhost:8081)” to the “frontend URL” of the master realm. `docker run -e KC_HOSTNAME=localhost -e KC_HOSTNAME_PORT=8080 -e KC_SPI_HOSTNAME_DEFAULT_ADMIN=localhost -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=admin -p 8080:8080 -p 8081:8080 quay.io/keycloak/keycloak:17.0.1 start-dev` --- _[View the full topic](https://forum.keycloak.org/t/kc-17-x-x-how-to-access-admin-ui-from-port-forwarded-internal-url-prevent-redirect-from-internal-url-to-kc-hostname/14917)._
