Top client shows only one IP (which I don't even recognize)

[arsaboo]

I started using this image on my Synology NAS and have been very happy with it...thanks a ton!

I just have one issue that I am not able to resolve, in the Top Clients section, I see all the requests from one IP address (172.17.0.1). This is particularly interesting, given that 172.17.0.1 is not an IP from my network (at least I don't recognize it). All the IP addresses in my local network have the format 192.168.2.*.

I was hoping that I could see the request per IP address. I am using and Asus router with Merlin firmware (if that helps). I am not sure if it is a bug or something that I need to fix at my end. Thanks for looking into it.

Is your Pi-hole accessible from the internet? Run pihole -d for a debug token.

Actually, that is a Docker internal IP address. @diginc would know more about why it's the only client.

Here's the debug token - smtw8e6m6a

Let me know if you want me to paste the log here. Thanks!

When a router cannot directly hand out DNS the only option is to have it relay. Mine does this too where my clients still point to my router and my router points to the pihole. the real addresses of the clients are lost in the process.

That is unfortunate. Here are few threads that I stumbled upon (although none of them are using a docker container):
https://www.reddit.com/r/pihole/comments/4rdg5m/top_clients_only_shows_router_ip/
https://www.reddit.com/r/pihole/comments/5gz6dz/trouble_getting_docker_based_pihole_to_work/

I guess, we will have to live with that.

[diginc]

@Mcat12 pointed out that is the docker gateway IP address so the router explanation isn't quite right.

What is your docker run command and what is the output of docker logs pihole | head -35

Also what version of docker?

[arsaboo]

I am using the latest version of Docker (1.11.2-0.325) on my Synology NAS and the latest version of the image that was released 8/10 hours back. I used the GUI to initiate the container. Here are the settings:

Looks like ServerIP didn't get set correctly. This is a known issue I need to address, before it would cause the docker to die instantly but s6 doesn't seem to be quitting immediately during container init script errors.

[arsaboo]

I added the ServerIP and it shows in the container details (192.168.2.113 is the NAS IP):

[diginc]

Does synology allows live editing of the environment variables? The "env_variables": [{ block you pasted from your docker inspect does not list ServerIP yet your screenshot obviously has it. Live editing values without informing the user you have to re-create a container may explain this.

[arsaboo]

The env_variables that I pasted was before I added the ServerIP. After your comment, I added the ServerIP. Here's the updated block:

[diginc]

is top client behavior the same still after ServerIP addition? does the startup log indicate it had any errors?
