+## HAProxy

+
+The frontend config:
+```# Public Service: SSLSecured (Frigate)
+frontend SSLSecured
+    bind XXX.XXX.XXX.XXX:443 ssl crt /etc/haproxy/certs/frigate.cert
+    mode http

+```
+The above config is created for a Layer 7 proxy (application layer, in this case http), if streaming the camera feeds are a little spotty or somewhat unstable, you can try to change the *mode* from http to tcp in both the frontend and backend config, which sets up a Layer 4 proxy (proxy by protocol). Make sure you change hdr(host) to req.ssl_sni in the frontend Condition to make the host based condition work on tcp traffic.

+
+This guide is for the OPNSense firewall add-on *os-haproxy* and is configured and tested on version 5.1 of the add-on on OPNSense 26.7.

+2. Add a Real Server under *Real Servers*;

+4. set *Type* to **static**;
+5. fill in the frigate IP in the *FQDN or IP* field;
+6. under *Common Options* fill *Port* with the port number for your Frigate (e.g. 8971) and
+7. Click **Save** to store this configuration.
+8. Under *Virtual Services* open *Backend Pools*;
+9. Add a *Backend Pool*;
+10. Fill in the fields *Name or Prefix* and *Description* but use something else then what you used under *Real Servers* otherwise if and when rules and conditions are needed it gets really confusing really fast, the use of them is out of the scope of this guide for a basic functioning haproxy add-on;
+11. set *Mode* to **HTTP (Layer 7)**;
+12. set *Balancing Algorithm* to **Source-IP Hash**;
+13. set *Servers* by choosing the *Real Servers* instance you added in step 2->6;
+14. Click **Save** to store this configuration.
+15. Under *Virtual Services* open *Public Services*;
+16. Add a *Public Service*;
+17. Fill in the fields *Name or Prefix* and *Description* but use something else then what you used under *Real Servers* otherwise if and when rules and conditions are needed it gets really confusing really fast, the use of them is out of the scope of this guide for a basic functioning haproxy add-on;
+18. Fill in the external address the haproxy instance will be listening on in *Listen Addresses*;
+19. set *Type* to **HTTP/HTTPS (SSL offloading)**
+20. set *Default Backend Pool* to the option carrying *the name you used in step 9*;
+21. check *Enable SSL Offloading*;
+22. Under *SSL Offloading* you set *Default certificate* to the certificate you added before you started following this guide;
+23. Click **Save** to store this configuration.
+24. Click **Apply** to reload the haproxy config on the service running.
+
+**NOTE: This will forward _ALL_ requests on port 443 to your frigate instance.** If that is not what you want or have more then one website alive behind the haproxy you will need to create a *Condition* to trigger when the right URL is used and a *Rules* rule to use the right backend under *Rules & Checks* when the condition is met. This is a useful hint for those who need it, though it is out of the scope of this guide.

+### Can I add a privacy mask to hide part of my camera's view?
+
+Frigate does not have privacy masks. [Motion masks and object filter masks](../configuration/masks.md) only affect detection, they don't hide anything in live view, recordings, or snapshots.
+
+Privacy masks are best configured in the camera's firmware settings so the area is blacked out before the video ever leaves the camera and no extra processing is needed. Check there first.
+
+If your camera does not support privacy masks, there is no efficient alternative. Frigate copies the camera's video into recordings and live view without decoding it, so part of the image can't be hidden without transcoding (re-encoding) the stream. This can be done with a custom ffmpeg filter in go2rtc, but it is not recommended. Every masked camera needs a continuous re-encode, which significantly increases CPU usage, especially for high resolution streams.

 This almost always means that the width/height defined for your camera are not correct. Double check the resolution with VLC or another player. Also make sure you don't have the width and height values backwards.
