+
+I've been enjoying Traefik for its auto-discovery of containers. The only problem is that for a couple containers such as Plex and HomeAssistant I have host networking enabled. This usually results in Traefik failing to forward the traffic properly.
+
+Having more fine grained control is exactly what Nginx is for!  I don't want to switch my whole setup to Nginx since that would be a lot of configuration files for every docker container. But I think having configuration files for containers that use host networking is manageable.
+
+In your docker-compose file first make sure that Traefik is disabled for containers that use host networking by adding the label `traefik.enable=false`
+
+```yaml
+  homeassistant:
+    image: homeassistant/home-assistant
+    container_name: homeassistant
+    hostname: homeassistant
+    network_mode: host
+    environment:
+      - PUID=1000
+      - PGID=1000
+    volumes:
+      - /Volumes/homeassistant/config:/config
+    restart: always
+    labels:
+      - traefik.enable=false
+```
+
+Then add a new section for `nginx` adding the domains that you wish it to manage in the labels
+
+```yaml
+nginx:
+ image: linuxserver/nginx
+ container_name: nginx
+ environment:
+   - PUID=1000
+   - PGID=1000
+ volumes:
+   - /Volumes/nginx/config:/config
+ restart: always
+ labels:
+   - traefik.http.routers.my-container.rule=Host(`plex.example.com`,`homeassistant.example.com`)
+```
+
+Now on the host system add the configuration files for nginx to consume. Example:
+
+```nginx
+server {
+    listen 80;
+    listen [::]:80;
+
+    server_name plex.example.com;
+
+    location / {
+        proxy_pass http://homelanip:32400;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+Similarly add a configuration file for `homeassistant` or any other service you have.
+
+Now for this example, the subdomains `plex.example.com` and `homeassistant.example.com` are managed by Nginx.
+
+To finish it off, `docker-compose start nginx`.
