Wait a few minutes, then log back in to Pi-Hole (eg: At the bottom of the page observe updated versions. Using an IP calculator you can configure this to a single ip in ip-range section of the command. In the previous post Recursive DNS Resolver with AD-Blocking Features Ive explained how to implement on a Raspberry Pi device a DNS resolver that blocks ADs and malicious sites (Pi-hole) and resolves names recursively (Unbound) without relying on official DNS servers like Google ones. This correctly shows all client IPs so Im very happy. I did this but it didn't work. I agree that ad blockers are really good! No port forwarding or anything is needed for your docker image just select Pi-hole as your network and delete bridge in the network section of the interface and set the ServerIP. Thank you so much for this guide. With the help of some articles I found online I made a docker-compose setup that is working great for me on my Synology DS918.

Screenshots are in Italian, but I think it will be easy to understand the equivalent in your language by looking at the positioning of the elements on the interface. I have a litle problem with "yaml"file. In this way weve doubled the Pi-hole servers, a first step toward redundancy (we still have a single Unbound server, so if RPi goes down, DNS resolution wont work, but lets focus on Pi-hole now and double Unbound in the next article). For this to respond we need to install WebStation. Right then, lets get to work, shall we? Pi-Hole will redirect blocked DNS names to the IP of the Synology NAS. It would break quickconnect functionality and also couldn't connect to the docker repository. If version numbers are blinking in red, it means that there is an official update available.

As we dont want to manually modify any of the DSM files we need to run WebStation with the Apache web server instead of nginx. Next we need to edit the ServerIP variable. Click on Action -> Erase (not Delete). Gn0s0z As youve seen above, weve overwritten the content of /etc/.pihole/advanced/01-pihole.conf file with our modified one in order to force cache-size to zero. Did you look into it further? Then, stop the pihole-pihole1 container, select it and click on modify and add a new Read-Only file mapping (not a folder mapping this time) in order to mount /volume1/docker/pihole/etc_.pihole_advanced/01-pihole.conf on /etc/.pihole/advanced/01-pihole.conf within the container: You can now restart the container and connect to the Pi-hole GUI running on http://your-nas-ip:8080/admin GUI, enter the admin password and theck on the Settings page that the DNS cache is set to zero: Now, you can configure Pi-hole as youve seen in the previous article and you can point the Unbound server running on the Raspberry as on the other Pi-hole setup as an Upstream DNS. In this way the Synology certificate and key Im mounting in the registry container will work fine because they match the FQDN name Im using to point the container.

You may need to set it to port #54 now as the docker file is showing. The only downside of this is it will only show an IP for the Synology in the pi-hole interface because the Synology uses pi-hole through a docker bridge being that it is unable to contact it through the macvlan. At the moment I just use custom DNS: 192.168.178.2 which is my OpenWRT that is hooked to my router modem. I did manage to get a cloudflared docker instance working but its not quiet how I would like it as I had to send the pihole to the router and have the router send requests from the pihole to the cloudflared container due to the Linux kernel blocking macvlan communication to the host. If you ssh into your Synology as a root user and use the following command: This will create a macvlan with the ip forced as a single ip (192.168..5) to use as a network for your docker image.You can then create your pi-hole docker image all through the UI now as this network will show up in docker.

My work around was to create my own file named resolv.conf and map this as a volume over the one inside the pihole container. After a bit of study Ive understood that the initialization script /root/ph_install.sh that is automatically executed by the container configures dnsmasq (the process that is responsible for Pi-hole dns resolution and caching) by replacing the values contained within /etc/.pihole/advanced/01-pihole.conf with the values contained in setupVars.conf and then it copies that file to /etc/dnsmasq.d/01-pihole.conf. Then, before starting a new container with this image, prepare the following folder structure (you can create it via File Station app): Note: /volume1 is a folder you can see via SSH CLI and its the folder containing the shared folders on your NAS. Time to replace it with a good old docker contai. Pretty cool, huh?

Create a new container using bridged networking, this guy is running in host networking mode, overly fancy setup, aka I dont need the lan ips that look stuff up. WebStation will process requests on port 80 however most of these will not be valid paths that the Synology is expected (due to Pi-Hole mis-directing these requests) and therefore will respond with 404 file not found errors. In this post Im going to take you through setting up Pi-hole on a Synology NAS using Docker. You must choose the first action, because we do not want to reconfigure it again. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Check DNS cache size, it must be ZERO if everything works asexpected, Erase the container in order to re-create it with an updatedimage, Subnet-to-Subnet SNAT/DNAT on Fortinet Firewalls with CentralNAT, Recursive DNS +AD-Blocker Part 2: installing Pi-hole without caching on Synology NAS withDocker, Recursive DNS Resolver with AD-Blocking Features | Networking Pills, Recursive DNS Resolver with AD-BlockingFeatures, Knock Knock, can you open the Firewall?

Launch Docker. Previously, the NAS would spend most of its life with the hard drives in hibernation, A) being quiet, and B) prolonging life. I tried a lot of guides, and nothing would work. Configuration is finished, apply the setup and let Synology Docker launch the newly created container. As Ive said in that post I have deployed two Pi-holes and two Unbound servers in my home network, to have a bit of redundancy when Im doing maintenance and to have a bit of fun The first Pi-hole+Unbound stack was deployed on an RPi3, so I had to choose another home-device that is active 24x7x365 for the second stack: my Synology DS218+ NAS with Docker was the perfect solution. The app will ask you about the initial configuration of the container. This will also give you the ability to run cloudflared or other DNS docker images that your pihole can use.

While the Pi is great for hacking on, its not the right kind of hardware to be used as a server in my opinion. This means the pi-hole needs port 53 (to actually respond to DNS requests) and port 80 (to host the Admin UI and to show the nice "blocked by pi-hole" images). Enable automatic restart, if you want, and then move to the Volumes tab: here we will mount the first two folders, ignore the third one, by pressing Add Folder, selecting the folders youve created before and mounting them on the correct paths with Read/Write permissions (I usually call the folder on synology as the path on which it will be mounted with dashes instead of slashes): Then move on the Port settings tab and expose the ports you want to be reachable to outside. I had that issue when first trying this install. We need to create two folders that we will map our Docker image to. This means the pi-hole needs port 53 (to actually respond to DNS requests) and port 80 (to host the Admin UI and to show the nice blocked by pi-hole images).
