You can change the DNS and default gateway configuration of a TCP/IP stack on a host. You can also change the congestion control algorithm, the maximum number of connections, and the name of custom TCP/IP stacks.

Note: You can change the DNS and default gateway configuration of the default TCP/IP stack only. Changing the DNS and default gateway configuration of custom TCP/IP stacks is not supported.

Procedure

  1. In the vSphere Web Client, navigate to the host.
  2. On the Configure tab, expand Networking and select TCP/IP configuration.
  3. Select a stack from the table, click Edit and make the appropriate changes.
