httpd fonctionne sur le port 443. Il s’agit du site web [example.com](http://example.com). Le forum doit fonctionner sur un sous-domaine [forum.example.com](http://forum.example.com). Quel port dois-je utiliser ?

Voici la sortie de netstat -alpn | grep 443

```
[root@vserver ~]# netstat -alpn | grep 443
tcp 0 0 0.0.0.0:8443 0.0.0.0:* LISTEN 28853/sw-cp-server:
