Client is offline with server as DNS

[peduso]

Hi there, thank you for building this lancache!!

I set up a Server with Linux Ubuntu 18.4.03

Then i used this tutorial: https://hoerli.net/lancache-der-cache-server-fuer-dein-netzwerk/ It is in german, but the commands are printed there.

The docker seems to be up and running. But when I change my client PC (Windows) to use the new server as DNS all Internet is gone. I can't find any website or log on my Steam.

root@server:/home/peter# hostname -I 192.168.2.12 172.17.0.1

How are you running the container(s)?

DNS Configuration

sudo apt install curl -y

sudo curl -sSL https://get.docker.com/ | sh

docker run --restart unless-stopped --name lancache -v /cache/data:/data/cache -v /cache/logs:/data/logs -p 192.168.2.12:80:80 lancachenet/monolithic:latest

docker run --restart unless-stopped --name lancache-dns -p 192.168.2.12:53:53/udp -e USE_GENERIC_CACHE=true -e LANCACHE_IP=192.168.2.12 lancachenet/lancache-dns:latest

docker run --restart unless-stopped --name lancache-sniproxy -p 192.168.2.12:443:443 lancachenet/sniproxy:latest

<!-- Paste your docker run command for the DNS container OR explain how you have setup DNS on your network to point to the container -->

Output of container(s)

I don't know what to paste here.

The server is still able to connect to the web and to ping google.com or whatever.

Do you have any idea how to solve this? What did I do wrong.

another hint maybe: While starting the server it gives this message:

"A start job is running for Wait for Network to be Configured"

systemctl show -p WantedBy network-online.target

gives

WantedBy=docker.service cloud-config.service cloud-final.service open-iscsi.serv
