**** This seems to be an ongoing issue for some as per the post bellow **** - changing to macvlan fixed my issue under "docker advanced"

## Version 6.11.5 2022-11-20 This release reverts a change which modified the wrong file. This resulted in not being able to select 'macvlan' custom docker network type. New installations only will now have 'ipvlan' selected by default. ### Docker - fix: Set IPVLAN as default only for new installations.

The ipvlan type is best when connection to the physical network is not needed. Please read this on implementing an ipvlan network.

The macvlan type of network allows direct connection to the physical network. Please read this on implementing a macvlan network.

I'm having the exact same problems as you, I have tried Versions: 6.11.2, 6.11.5 and Version: 6.12.0-rc8. I have noticed via other posts that people with HP Microservers are complaining about this, I have an HP Gen 8 Microserver.

Also tried the following DNS, access is availble but I cannot update anything, ping works for a couple of minutes then "Destination Host Unreachable" :-

194.168.4.100, 194.168.8.100 which are Virgin Media.

1.1.1.1 and 1.0.0.1 Cloudflare

8.8.8.8 and 8.8.4.4 Google

As well as the suggested opendns in DNS post on the forum.

Works and then stops working. Syslog seems to be full of bootstrapDNS("derp5d.tailscale.com", "43.245.48.250") for "log.tailscale.io" error: Get "https://derp5d.tailscale.com/bootstrap-dns?q=log.tailscale.io": context deadline exceeded and others, might not be related, I have removed tailscale.

Lastly, I can ping the server from any device and the server can ping the gateway.

I have tried everything suggested by the developer in this post:-

I'm baffled.
