Forgejo serve itself without a reverse proxy with HTTP and HTTPS.
HTTP transport is used by default, to turn on HTTPS transport set in `SERVER` section of the configuration `PROTOCOL=https` and either set `CERT_FILE` and `KEY_FILE` or let Forgejo manage the certificates with `ENABLE_ACME=true`
You may wish to place your Forgejo instance behind a reverse proxy. A reverse proxy is a server that accepts requests from the outside and routes them to internal services, like Forgejo.
## nginx
### Basic HTTP
To set up a basic HTTP reverse proxy in nginx, create a file `forgejo.conf` in `/etc/nginx/conf.d` and add the following configuration:
Make sure to set the Forgejo `ROOT_URL` configuration key to the URL _with_ the subpath, otherwise links generated by Forgejo will be broken.
### HTTPS
When using a reverse proxy, it's usually easier to let the proxy handle HTTPS. It's easy to set up HTTPS on nginx.
#### HTTPS with Certbot
To set up HTTPS with Certbot, first set up an HTTP reverse proxy with the configuration above and ensure that it works as expected. To use HTTPS you need to have a domain name.
Then, install [certbot](https://certbot.eff.org/). When running certbot, select the domain name that your Forgejo instance is hosted under, and choose automatic installation. This should automatically set up HTTPS on port 443 and a redirect on the old port 80.
You may wish to change the `ROOT_URL` configuration key to the HTTPS protocol so links generated by Forgejo automatically use HTTPS.
#### HTTPS with manually installed certificates
If you have obtained certificates from elsewhere or have chosen not to let certbot automatically install them, make the following changes to the configuration file:
Generate an SSL configuration at [mozilla](https://ssl-config.mozilla.org/#server=nginx), and add the SSL parameters to your configuration file. Make sure to replace the paths in the example with paths to your certificate files.
**Add a redirect from HTTP**
Outside the server block, add this redirection block:
Next, enable the site with `a2ensite 100-forgejo.conf` and enable the proxy modules with `a2enmod proxy proxy_http`. Finally, restart the apache server.
### HTTP with a subpath
If you want to serve Forgejo on a subpath, e.g. on `http://example.com/forgejo`, use the following configuration:
ProxyPass /forgejo http://127.0.0.1:3000/ nocanon # Change /forgejo here to your desired subpath.
</VirtualHost>
```
Make sure to set the Forgejo `ROOT_URL` configuration key to the URL _with_ the subpath, otherwise links generated by Forgejo will be broken.

#### HTTPS with manually installed certificates
If you have obtained certificates from elsewhere or have chosen not to let certbot automatically install them, make the following changes to the configuration file:
**Change the listening ports**
Change `<VirtualHost *:80>` to `<VirtualHost *:443>`.
**Add the SSL certificate information**
Generate an SSL configuration at [mozilla](https://ssl-config.mozilla.org/#server=apache), and add the SSL parameters to your configuration file. Make sure to replace the paths in the example with paths to your certificate files.
**Add a redirect from HTTP**
Outside the `VirtualHost *:443`, add this configuration:
Forgejo supports Reverse Proxy Header authentication, it will read headers as a trusted login user name or user email address. This hasn't been enabled by default, you can enable it with
The default login user name is in the `X-WEBAUTH-USER` header, you can change it via changing `[security].REVERSE_PROXY_AUTHENTICATION_USER` in app.ini. If the user doesn't exist, you can enable automatic registration with `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true`.
The default login user email is `X-WEBAUTH-EMAIL`, you can change it via changing `[security].REVERSE_PROXY_AUTHENTICATION_EMAIL` in app.ini, this could also be disabled with `ENABLE_REVERSE_PROXY_EMAIL`
If set `ENABLE_REVERSE_PROXY_FULL_NAME=true`, a user full name expected in `X-WEBAUTH-FULLNAME` will be assigned to the user when auto creating the user. You can also change the header name with `[security].REVERSE_PROXY_AUTHENTICATION_FULL_NAME`.
You can also limit the reverse proxy's IP address range with `[security].REVERSE_PROXY_TRUSTED_PROXIES` which default value is `127.0.0.0/8,::1/128`. By `[security].REVERSE_PROXY_LIMIT`, you can limit trusted proxies level.
