|`UFW_EXTRA_PORTS` | Allows the comma separated list of ports through the firewall. Respects UFW_ALLOW_GW_NET. | `UFW_EXTRA_PORTS=9910,23561,443`|

### Health check option
Because your VPN connection can sometimes fail, Docker will run a health check on this container every 5 minutes to see if the container is still connected to the internet. By default, this check is done by pinging google.com once. You change the host that is pinged.
| Variable | Function | Example |
|----------|----------|-------|
| `HEALTH_CHECK_HOST` | this host is pinged to check if the network connection still works | `google.com` |
### Permission configuration options
By default the startup script applies a default set of permissions and ownership on the transmission download, watch and incomplete directories. The GLOBAL_APPLY_PERMISSIONS directive can be used to disable this functionality.
