If you are self-hosting at home and without a VPN, you need to forward ports on your home router ("Internet box"). If you want a short explanation on what is and why you need port forwarding, have a look to [this page](port_forwarding).

### 0. Diagnose ports opened

The new diagnosis tool introduced in 3.8 can be used to diagnose that ports are
correctly exposed.

### 1. Access your box/router administration interface

Your box/router admin interface is usually reachable via http://192.168.0.1 or http://192.168.1.1. Then, you will probably need to authenticate yourself with your internet server provider's credentials.

### 2. Find the local IP of your server

Identify what is thei *local* IP of your server, either :
- from your box/router interface, which might list devices connected
- from the YunoHost webadmin, in 'Diagnosis', section 'Internet connectivity', click on 'Details' on the IPv4 report.
- from the command line in your server, by running `hostname -I`

A local IP address typically looks like `192.168.xx.yy`, or `10.0.xx.yy`.

The local IP address needs to be static, so that the port forwards that you are going to configure in the next step will always reach your server. You should go into your box/router and make sure that the local IP address of your server is static instead of dynamic.

### 3. Forwarding ports

In your router admin interface, look for something like 'router configuration' or 'port forwarding'. The naming differs among the various kinds of boxes.

Opening the ports listed below is necessary for the various services available in YunoHost to work. For each of them, the 'TCP' forwarding is needed. Some interfaces refer to 'external' and 'internal' ports : these are the same in our case.

* Web: 80 <small>(HTTP)</small>, 443 <small>(HTTPS)</small>
* [SSH](/ssh): 22
* [XMPP](/XMPP): 5222 <small>(clients)</small>, 5269 <small>(servers)</small>
* [Email](/email): 25, 587 <small>(SMTP)</small>, 993 <small>(IMAP)</small>

If you use both a modem and a router, then you need to do the following:
1. first on the modem (the box closest to the internet) create rules to forward the above ports to your router;
2. then on the router (the box between the modem and your devices) create rules to forward the above ports to the static IP address for your server.

<span class="glyphicon glyphicon-warning-sign"></span> Some internet service providers block port 25 (mail SMTP) by default to fight spam. Some other ISP don't allow to use port 80/443 (web) freely, though it's less likely. Depending on the ISP, it might be possible to open them in the admin interface... Check [this page](/isp) for more info.

## Automatic port forwarding / UPnP

A technology called UPnP is available on some internet boxes / routers and allows to automatically forward ports by the machine who needs them. If UPnP is enabled in your local network, then running this command should automatically open the port for you :

```bash
sudo yunohost firewall reload
```
