  Network configuration / routing / two network interface cards / NAT - leased / dedicated Dell R210 running VMware ESXi 5.1.0 build-799733

  Hello

  I'm trying to understand how to configure a dedicated server of Dell R210 rented running VMware ESXi 5.1.0 build-799733

  This dedicated server is rented www.online.net and sits somewhere in France. One of its network adapters have an IP public 62.210.177.20x. The other NIC is here, but I do not understand how it is configured. According to the www.online.net portal, the other NETWORK card has or should have an IP 10.90.116.20x. And I am obviously set up is to have some virtual machines running and be able to access the Internet. I have access to the console of the server Dell through iDRAC and since I could see, one of the network adapters in the IP is 62.210.177.20x defined, and the other has been shown out of service. I managed to make it appear the other interface but I cannot find anywhere how to assign the IP address 10.90.116.20x to this 2^nd network adapter. But then again I don't even know if I should or if I need to assing a IP address to this 2^nd network adapter. What is the cable connected even for this 2^nd NIC? I do not know. Should it be - I'm not either. I don't know French and manuals/instructions on www.online.net are in French. I can try an online translator, but I don't think that what I'm looking for is explained. How do I get this set up? I have to do something about the ESXi on the server console? This interface 2^nd should be in place, or it must be down as if it was originally? Yesterday after watching someone videos on YouTube, I added the second virtual switch and moved the virtual hosts of this switch 2 and he entrusted the 2^nd NIC. But that 2^nd NIC had a red X next to it probably indicating that it was disconnected the 2^nd form virtual switch. Today and now I have managed to access the ESXi console server through iDRAC, I bring the 2^nd NIC, and now both network adapters are assigned to the virtual switch 1^st . But I think that a NIC should be attributed to a single switch and the other card NETWORK on the 2^nd switch. I'm just a desktop guy with enough knowledge to be dangerous J if you / someone put in steps how and where to set them up it... PLEASE

  Thanks in advance

  Network configuration

  • VMware vSphere Hypervisor is an "operating system" for pure virtualization and support NAT or routing. Therefore, only a real bridge configuration can be used.
  • To use a subnet additional IP must be configured as a router VM.

  If I understand the above, I need to show some VM and set up as a router? If the virtual machine that will act as a router must have two network interfaces, where it is connected to a switch and the other to the other switch network card. Am I do? The YouTube video that suggested, but I thought that maybe / somehow ESXi can route packets between the two network cards, but from what I read, ESXi can route packets. Do I need to order an additional / extra / 2nd IPv4 address so that it can be assigned to the interface of the router?

• Critical of my network to new ESXi server configuration

  Hi all, I would like to see if someone sees a problem with the following configuration for 2 new servers which will join my Cluster.  I want to so 2 way balancing redundancy by using etherchannel.  I have 5 total physical NETWORK adapter each ESXi server.  Since they will be ESXi, no service console.  I intend to install NIC1 and NIC2 etherchannel and trunk of ESXi to spend blade1 in our Cisco 6509.  I intend to install NIC3 and NIC4 etherchannel and trunk of ESXi to switch module2 in our Cisco 6509.  I intend to connect 5 NIC for module1/2 in our 6509 using a VLAN dedicated to be used only for vmotion traffic.  Virtual MACHINE will be connected to a vswitch with uplinks by using etherchannel groups.  Is it a solid plan or suggest something different?  Please see the diagram attached clarification (or possibly more confusing)

  Thank you!!

  To answer your question on etherchannel, you are right when you say that you'd be using the total card network bandwidth, but you must enable IP Hash-based like politics that comes with a bit of overhead, not much but it's there.  Also, do you have VMs that require the use of more than 1Gbps of bandwidth actually?  If you go this route, if not then I would just create a Port Channel on your 6509 and add as appropriate ports to switch to this channel port then set the channel Port in trunk mode.  At this point, just use VLAN tagging on PortGroup level to mark up your traffic to your virtual machines.  If there is no need for tagging VLAN and then just set the access ports switch vlan on your pSwitches.  Then use the default NIC Teaming-> Load Balancing political originating virtual port ID.

  I have actually made vMotion and management both before.  I think it really boils down to your convenience, but I think that best practices States to separate the two.

  If you have found this helpful at all prices please points using the correct or useful!  Thank you!

• Networking ESXI establish two vswitches and 2 NICs on different networks.

  OK hope someone has an idea.

  Have two network cards and just connect the second network card but my setup requires that the first NIC physicle

  10.10.0.0 network, 255.255.255.0 subnet, Gateway, Vswitch 10.10.0.105 0.

  the second nic physicle

  100.100.0.0 network, 255.255.0.0 subnet, 100.100.0.1 gateway Vswitch 1

  I need the machine virtual first Vswitch network and some on second Vswitch network.

  At the moment I don't see how to set the ip address of the second network card or the gateway?

  Is there a way to do this?

  I have the updated Vswitches in place ok and network adapters are attached to the different vswitches.

  When a physical NETWORK card is assoiciated with a vSwitch, he is forced to behave like a shared on a physical switch port. However, there is more no uique to the physical NETWORK adapter configuration. It passes the traffic of the VMs and the core of the virtual machine to the physical network as an uplink. MAC addresses and IP addresses inside the frames come from virtual NICs attached to the virtual switch.

  You define IP addresses and default gateways within the virtual machines and any VMkernel ports connected to the virtual switch.

  Another way of thinking, is pretending the ESXi server has swallowed a bunch of switches and cards network is now the switch ports. You connect a box full of switches to your physical infrastructure, not a 'normal' server

• Cannot access ESXi server via network

  Hello world!

  We have a HP C7000 Encolosure with 4 BL460c Gen 8 blades in front size of it. Back size of the C7000, we have 2 SAN Switch, 2 switch HP BLc GbE2c layer 2/3 and 2 Onboard Administrator Module.

  Everything is working fine with IP addresses like this:

  OA active:

  IP address: 172.16.0.253

  STANBY OA:

  IP address: 172.16.0.254

  Server Blade BL460c Bay 1:

  The IP address of the ILO: 172.16.0.10

  Server Blade BL460c Bay 2:

  The ILO IP address: 172.16.0.11

  BL460c blade Bay 9:

  The ILO IP address: 172.16.0.19

  Server Blade BL460c Bay 10:

  The ILO IP address: 172.16.0.20

  We can ping pc that connected to the port of ILO on Onboard Administrator (OA) IP addresses above. (I can it call PC MANAGE?)

  Continue, we access OA via Web https://172.16.0.253 use of , then Console integrated to control 4 Server blades. We have mounted image ESXi 5.1 U1 and successfully installed on 4 servers blade.

  We manually config IP address on each ESXi Server (like this):

  BL460c Server Blade on Bay 1 as server ESXi 1:

  IP address: 10.0.0.11

  BL460c Server Blade on Bay 2 as server ESXi 2:

  IP address: 10.0.0.12

  BL460c Server Blade on Bay 9 as a server ESXi 9:

  IP address: 10.0.0.19

  BL460c Server Blade on 10 Bay as a server ESXi 10:

  IP address: 10.0.0.20

  Now we can ping server to another server ESXi ESXi 1. I mean 4 Blade Server can ping together.

  BUT:

  -We can not ping servers to blade PC of manage (that PC connect to the port of ILO on OSTEOARTHRITIS. In this scene, MANAGE PCs has the IP 172.16.0.100/16)

  -We unplug the network cable from the port of iLO, then connect it to the port number 24 on HP BLc GbE2c LY 2/3 switch, then address IP of the PC to MANAGE the 10.0.0.100/24 value. Always the same, can only access servers

  Can someone explain to me how to access this server (ping, http, etc...). Do we have to config switch HP BLc GbE2c LY 2/3? We read many many guide on the HP website, but they have not mentioned about routing or switch to configure

  Thanks in advance!

  It's my mistake!

  My servers have 2 connections FlexLOM. That a connection has been enabled for 'network management' in ESXi. I do not understand, then I activated 2 connections. That cause outside the network can not access them.

  I just disabled a single connection and everything works perfectly.

  I thank everyone!

• ESXi server heartbeat ips 5

  Could you help me understand

  Network team reported if stirring in the router logs have been 0050.56b2.6200 > 10.101.192.57 > xyzserver1

  16:44:36: johny: 0050.56b2.6201 > 10.10.19.58 > xyzserver2

  15 h: johny: 0050.56b2.000f > 10.10.19.40 > xyzserver3

  I checked the logs and found no differences that server changed their ips on the day and the time network team mentioned. What could be the reason. all esxi servers connected to vlan 15 on the physical switch and service of esxi console have not configured the vlan tag is set to None.

  Where I can go and find the reason or network router number?

  the mac belongs to the vm window that needs to be migrated between esx servers in the cluster and this machine virtual mac has been upsized 7 times on 5/13.

  is this a big deal? is this normal... right?

  If you know that the virtual machine with the actual MAC address is in fact proposed by the DRS / vMotion several times that day and you know the two switch ports mentioned in the newspaper is connected to two ESXi hosts, so everything is perfectly normal.

  It may seem a little unusual for the physical switch that a MAC address moved several times during the day, but nothing more "strange" that a user to roam a large desk and connection to the physical network of the different places, sends out packets and then disconnect and connect later to another physical position of the network. The switches should have no problem with this fact.

  The important thing is that the MAC address must never be learned from different places at the same time. This would mean that you have one loop two network layer, which is very dangerous.

  In your situation, I would say you can safely ignore the switch error log.

• Connect two VSphere ESXi 5.0 with crossover cable

  Hi all! A newbie in the ESXi 5.0

  I configured both servers of VSphere ESXi 5.0 with two network adapters on each server, the first NETWORK card acts as a virtual Internet switch, and the other NETWORK adapter serves only the link of communication (Heartbeat) between two VSphere Esxi 5.0 using crossover cable.

  My question is, how can I create such change in VSphere in a problem of communication between these 2 servers with a crossover cable? I would like to connect my (CentOS 6) VMs on each server via this network adapter with cable modem Simulator for the purposes of the communication of pulsation. I know how to create a normal vSwitch who can communicate with the Internet, but I have no idea how to create a switch for the NICs connected with a crossover cable.

  Please drop me a line if you know how.

  P.S. The idea to use the crossover cable rather than use the simple ethernet cable is the cable eliminates the overhead and to avoid the lack of packages due to the processing time of the switch.

  I know not how to create one with ordinary vSwitch to establish a connection with the Internet, but not this vSwitch with crossover cable.

  There is no difference. Build a vSwitch as your normally would, including the NETWORK card that is connected via a crossover as your uplink cable.

• Travel/cloning between two hosts ESXI VM

  Hello

  I have two hosts ESXI 4.1 with VSphere Essentials for VCenter license. I'm not able to move the virtual machine to one ESXI host to another (power off). It is not supported with VSphere Essentials license? Data warehouses can be shared between the two ESXI hosts?

  What is the size of your virtual machine, what is the speed of the network and how your local storage looks like? Using RAID? How many disks and RAID level? You have a battery attached to the RAID controller write buffer cache?

  The waiting period does not necessarily mean the tasks does not work. Often it is only a delay in the vCenter Server GUI, but the process is still running and you just need to be patient. You see the files being created on the target data store?

• Export the VM of ESXi to 'not connected' ESXi Server using converter

  Hi all

  Sorry for the newbie question - I've seen a lot of messages about the export of a machine virtual workstation or player, etc, but I couldn't find one for my purpose.

  We need to export a virtual machine that was created on a server ESXi Server ESXi in another place that has no network connectivity between them using the converter v 4.01 Standalone (?). The idea is the following: export image, copy the files on USB key, send to a remote site, they will import image on their server ESXi (same version).

  What is the best way for me to do using the converter?  I thought that I could simply select the VMWare Infrastructure Server as a destination, but that seems to be an option only if you have the remote a plugged into the network.

  Does anyone have suggestions as to the export type that may possibly be more coherent than the others? That is to say; export as "vmware workstation or another vmware virtual machine" say vs "virtual appliance"?  Are just as reliable a prospect of import export and then?

  Thanks in advance!

  D

  If the two ESXi is the same version that you can do is go to the browser data store and download all the VMS in the USB drive and then go to Site 2 and upload is via the browser of data store. Browser for the .vmx and save the virtual machine.

  If you still want to use vmware converter to format of workstation converter so that the destination can be selected as USB key, then a workstation to vmware infrastructure in Site 2.

• VM in DMZ and LAN on the same ESXi Server VM

  It is advisable to run two virtual machines on a physical ESXi Server considering only

  a VM THAT is connected to the DMZ (demilitarized zone) and another VM is connected to the local network.

  For example, a virtual machine can be a gateway mail server in the DMZ and

  another VM can be located in LAN mail server.

  ESXi box has multiple network cards, so a single card could be connected to the DMZ and others to the local network.

  Is it dangerous from the point of view of security?

  It becomes really dangerous if you have a virtual machine that is connected to two networks at the same time if not online, there is no way known to cross borders. Other that that, you should be good to go

• correct settings for two networks?

  I have a desk that has a building at each end of the city.  I have a wireless bridge that connects the buildings.  Each building is on its own ip configuration and has its own internet connection.  I have a server for A construction program.  I want to be in the B building clients connect to this server, but still use internet and print to printers on their own network.

  Right now the wireless bridge has the same addresses as a. construction I also fooled with assignment of two for each clients network adapter ip addresses.  This works fine, except that I see only computers B building in the Working Group, and I don't know if its using internet of B building or A building.

  Building A uses 192.168.5.x - 255.255.255.0 - 192.168.5.1

  Building B uses 192.168.10.x - 255.255.255.0 - 192.168.10.1

  Any help is appreciated, and I can give you more information if necessary.

  Hello

  I don't know what hardware you are using specifically. Regular Bridging could not do you need a device for routing between two independent

  Networks that are on a different subnet.

  If the two networks are bridge successfully to act as a coherent networks (same subnet), choose which Internet connection would be used by each computer can be made by assigning static IP addresses and gateway entrance to TCP/IP on the computer the IP number of the router as the Internet should be used,

  Passing by the details beyond the scope of the forum of support to end users. If the above do not help, you should get a consultant on-site.

• Communication between two network cards on windows 2003

  Hi all

  I need your help.

  I have a machine virtual windows 2003 with two network adapters.

  NIC 1 - external - 192.168.1.101

  Map NETWORK 2 10.10.10.1 - internal -.

  I've configured to operate as a DC and DNS serving 10.10.10.x network.

  DNS is configured to resolve before on 192.168.1.1 as redirector DNS requests.

  I have other machines connected to the 10.10.10.x network.

  They can ping 10.10.10.1, they can ping 192.168.1.101 but not 192.168.1.1

  I want to just be able to talk to 192.168.1.1 and be able to access the internet.

  No firewall between the two.

  Command-line may help, but I would need your help.

• two networks showing on vm when one network card installed.

  Hello

  I have a virtual computer whose use have two network adapters, a network card was on vm
  a vlan 20 of the network and the other was on vm two network vlan 21, one of the
  interface cards network has been disabled. I have now deleted one of the network adapter, but when I look at the
  standard switch it is always showing the virtual machine to be on both networks. If I look at
  the summary of the virtual machine, it also appears
  It is in the two networks. It is in sight for VI client connected to
  vCenter. If I connect the host to the virtual machine runs then all
  properly, shows a network card in a network.

  Any ideas how to fix this seen vcenter?

  If the virtual machine has Active snapshots, the deleted virtual network adapter will display until you delete the snapshot. The reason is that ESXi must remember the configuration of the 'old', where you decide to go back to a snapshot that was still the second NETWORK card in use.

• is it necessary to connect my ESXI Server

  Hello

  is it necessary to patch my catch up on ESXI?

  I have two server ESXi in my VCENTER. is it necessary to connect these two ESXi server each month something mineral?

  Both work fine until one year now...

  Well, it is recommended to keep the software up-to-date (security, bug fixes,...). However, it really depends on your needs and requirements. Personally, I usually check the release notes for critical issues that could affect me, in order to determine whether the patches should be applied immediately or if I wait until the next updates are released. I know people/companies who perform the same bits without problems because the environment has been installed (years)

• Access NAS storage of ESXi Server using VMKernel Port?

  Hello

  I would like to know the best procedure to connect to the NAS storage of ESXi host 5. I am able to connect to the NAS storage according to the screenshots listed in the link below.

  http://www.tintri.com/blog/2011/11/connecting-vSphere-to-NFS-the-easy-way/

  But, I saw different configurations in the past where port dedicated VMkernel is assigned to NAS and all storage goes into network 10 G. I try to do the same and created a VMkernel for NAS port. But I don't think that traffic is going over there as it is not used at all.

  I gave the IP address of the ESXi server on the NAS box to get access. I couldn't give address IP VMkernel sideways NAS. How can I make use of this IP VMKernel dedicated NFS storage?

  I want to implement the best way to pass NAS 10 G network traffic. In addition, How can I test if storage traffic crosses VMkernel port?

  Suggestions needed.

  Virtualinfra is right that you must use a different subnet for NFS traffic. You masked the IP range, so I don't see what you use, but make sure that the vmkernel and storage using a single subnet, not the management subnet. If you get an error, your use of a subnet that goes out the default gateway of the management port, or that you are using the same subnet.

  I wrote a few articles on the use of NFS with vSphere: http://wahlnetwork.com/2012/04/19/nfs-on-vsphere-a-few-misconceptions/

  Also, make sure that the vmnic can route traffic on that subnet, as in the case of the use of VLANs.
