Hi dear Community.

 

I ask again for your help as I am losing my mind right now. I set up a pihole docker container and started using it for a while as the DHCP server. It worked well for quite some time but then started to randomly losing internet connection and even losing connection to the gateway. My guess here was that it was because of my cheap Huawei LTE Router. So I started using the DNS settings on the router and now my Unraid server no has really unstable internet connections and is losing it constantly or the request are timing out.

 

Docker containers are not able to update anymore or establish a connection:

 

Pings are looking fine though:

 

Traceroute not so much:

 

Those are all my network settings

Unraid static ip:

#

Router DHCP settings:

 

Pihole

 

Thanks for your time and help

I did the following. I set the unraid server static DNS to 1.1.1.1 and the Router DNS to the Pihole IP. Everything is now working fine right now. It seems that setting the pihole server address as DNS in the UnRaid Server Network settings during the changes and the docker containers not running that it creates some sort of confusion.

UPDATE:

 

For anyone having issues, I found the topic for Tips and Tweaks and corresponding wiki which mentions of two network settings to try to disable them:

 

https://wiki.unraid.net/index.php/Tips_and_Tweaks#Disable_network_offloading

 

The options are Disable network offloading and Disable network flow control. After disabling I don't occur to have the DNS issues after 24 hours.
