4 NICS 4 different networks

Hello, I have installed a ESXi 6.0.0

It has 4 NICS.

At the moment I have a w7 virtual machine and a Ubuntu, W7 detects all NICs. I will use it to connect remotely to this virtual machine to control and monitoring all networks.


I need to connect each one nic to one different network

10.X.X.X/24  I use one IP (10.X.X.189) here to connect with the vSphere Client. Its default gateway is 10.X.X.80

10.X.X.X/24

172.16.156.0/24

192.169.1.0/24

W7 detects all NICs and I configured them as this:

10.X.X.X/24 IP (10.X.X.189) GW 10.X.X.80

10.X.X.X/24 IP 10.X.X.202 GW 10.X.X.1

172.16.156.0/24 IP 172.16.156.202  GW 172.16.156.1

192.169.1.0/24  IP 192.169.1.202 GW 192.169.1.1


When I try to ping a host in the 172.16.156.0/24 network, it tries to go through the default GW (10.X.X.80), so the first DNS server answer me....it can'y obviously find anything.

If I delete the default route 0.0.0.0 from the Route Table and configure a new one with the command

add route 172.16.156.0 mask 255.255.X.0 172.16.156.1 if 12 the 172.16.156.202 host answer me as destination unrecheable

I also configure the VMWARE networking as this:

What can I do?

What silly thing I'm not configuring properly?

Hello,

I moved this to the vNetwork forum for better answers.

A few things. If it is a W7 VM, it would not detect all NICs, so I assume this is a W7 Physical Machine. Is the Host Dual booted? Are you trying to run ESXi within VMware Workstation? Can you give us more on the actual configuration of the ESXi 6.x stack?

Virtual NICs connect to Virtual Switches which uplink to the physical NIC, which connects to the physical switch. You have 4 NICs showing, two are not working (the red X), and two are but you split them across various switches. Is the ordering of pNIC to vSwitch correct? Start there.

Each pNIC could carry all 4 networks depending on what is done upstream of them. So are you using VLANs of just subnets?
