Firewall disabled ?

VMware Tools installed ?

VMXNET3 interface in use ?

Both VMs are using the same virtual machine network ?

can your VMs ping the host ?

can your VMs ping the host ? No

My VM is using 192.168.10.0/24 network.

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

what is the host IP Address ?

Can you answer the other questions I asked, thanks.

Firewall disabled ? yes

VMware Tools installed ? No. I am installing now.

VMXNET3 interface in use ? yes

Both VMs are using the same virtual machine network ? I am building another VM now as you want me to check this part.

can your VMs ping the host ? No

Can your VMs ping anything ?

Do you have any other VMs ?

Here is my switch configuration for VLAN 10

interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,10,1002-1005
switchport mode trunk
spanning-tree portfast
!

Here is router configuration

Router#sh ip int brief

is the host on VLAN 10 ?

is the hosts IP Address - 192.168.10.x ?

is the default gateway IP Address 192.168.10.1 on VLAN 10

can your ESXi Host, ping the default gateway ?

Here is the Host configuration:

NIC0 is connected to Trunk port, (vSwitch1)

Port group associated to vSwitch1 with VLAN 10.

Please see attached configuration pictures.

is the host on VLAN 10 ? No

is the hosts IP Address - 192.168.10.x ? No

is the default gateway IP Address 192.168.10.1 on VLAN 10
YES

can your ESXi Host, ping the default gateway ?
YES

~ # esxcfg-route -l
VMkernel Routes:
Network Netmask Gateway Interface
192.168.2.0 255.255.255.0 Local Subnet vmk0
default 0.0.0.0 192.168.2.254 vmk0

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

so which is the default gateway

192.168.2.254

or

192.168.10.1

So if the ESXi host can ping 192.168.10.1, it must be going through another router.

if VLAN 10 is native to 192.168.10.1,

Routing Config or VLAN10 network is incorrect.

Hi

I did reconfigure everything on the cisco switch.

VLAN 10 - carries ESXi Management Traffic

VLAN 20 - Windows

VLAN 40 - unix

works now.

keeping ESXi host on VLAN1 native VLAN created issue.
