If you're using Docker, you'll also need to add an additional jail to handle the **FORWARD**
chain in **iptables**. Configure it in `/etc/fail2ban/jail.d/gitea-docker.conf`:
```ini
[gitea-docker]
enabled = true
filter = gitea
logpath = /home/git/gitea/log/gitea.log
maxretry = 10
findtime = 3600
bantime = 900
action = iptables-allports[chain="FORWARD"]
```
Then simply run `service fail2ban restart` to apply your changes. You can check to see if
fail2ban has accepted your configuration using `service fail2ban status`.
Make sure and read up on fail2ban and configure it to your needs, this bans someone
for **15 minutes** (from all ports) when they fail authentication 10 times in an hour.
