I tried to deploy the Data Connector (DC) for my Infoblox environment. The appropriate IP should be in the network 172.17.6.0/24
If I try to ping the Default-Gateway (172.17.6.1) from the DC it is not reachable. From other VMs in the same IP-Subnet it is reachable.
If I ping for example 172.17.0.1, which is not pingable in my real network, is reachable.
Is it possible that the VM uses Docker with the Subnet 172.17.0.0/16 internally?
If yes that would explain the strange reachability behaviour of the VM.
Your assumption is correct.
"docker0" interface in Data Connector uses the 172.17.0.0/16 Network by default.
This is the reason why you are unable to ping the Gateway which falls under this Network.
To the best of my knowledge, the docker0 Interface in Data Connector is hardcoded and we do not have an option to change this.
