VMware vSphere ESXi


  • DHCP assigns IP and does not assign default network.
  • The tether.debug log file will show that the gateway for the DHCP response is nil.

INFO DHCP response: IP=, SubnetMask=ffffff00, Gateway=<nil>, DNS=[], Lease Time=2h0m0s

Note: The tether.debug is located on the VMFS datastore that the VM container's working directory.

  • The DHCP discovery will not have "route" as one of the requested options when viewing a data level packet dump.

VMware vSphere Integrated Containers 1.0.x


VIC 1.1.1 caches the network scope for dynamic networks causing the DHCP to assume that the default gateway is defined statically.


To resolve this issue, upgrade the VIC appliance and then the VCH endpoint VM.

  1. Upgrade the VIC Appliance -  Upgrade the vSphere Integrated Containers Appliance
  2. Upgrade the VCH endpoint VM - Upgrade Virtual Container Hosts

Additional Information

Containers on Container Networks have no internet connectivity after >2 Containers are started and have obtained IPs
