5 On the NIC settings page, set the MTU for the network adapter.
6 With IPv4 enabled, in the IPv4 settings section, select the method by which IP addresses are
obtained.
Option Description
Obtain IPv4 settings automatically Use DHCP to obtain IP settings. A DHCP server must be present on the network.
Use static IPv4 settings Enter the IPv4 IP address and subnet mask for the VMkernel adapter.
The VMkernel Default Gateway and DNS server addresses for IPv4 are obtained
from the selected TCP/IP stack.
Select the Override default gateway for this adapter check box and enter a
gateway address, if you want to specify a different gateway for the VMkernel
adapter.
7 With IPv6 enabled, in the IPv6 settings select an option for obtaining IPv6 addresses.
Note The IPv6 option does not appear on hosts that do not have IPv6 enabled.
Option Description
Obtain IPv6 addresses automatically
through DHCP
Use DHCP to obtain IPv6 addresses. A DHCPv6 server must be present on the
network.
Obtain IPv6 addresses automatically
through Router Advertisement
Use router advertisement to obtain IPv6 addresses.
In ESXi 6.5 and later router advertisement is enabled by default and supports the
M and O flags in accordance with RFC 4861.
Static IPv6 addresses a Click Add IPv6 address to add a new IPv6 address.
b Enter the IPv6 address and subnet prefix length, and click OK.
c To change the VMkernel default gateway, click Override default gateway for
this adapter.
The VMkernel Default Gateway address for IPv6 is obtained from the selected
TCP/IP stack.
On the IPv6 settings page, click Advanced settings to remove IPv6 addresses. If router advertisement
is enabled, removed addresses from this origin might reappear. Removal of DHCP addresses on the
VMkernel adapter is not supported. These addresses are removed only when the DHCP option is
turned off.
8 On the Analyze impact page, verify that the changes made to the VMKernel adapter will not disrupt
other operations.
9 Click OK.
Overriding the Default Gateway of a VMkernel Adapter
You might need to override the default gateway for a VMkernel adapter to provide a different gateway for
services such as vMotion and Fault Tolerance logging.
Each TCP/IP stack on a host can have only one default gateway. This default gateway is part of the
routing table and all services that operate on the TCP/IP stack use it.
