• How to set up a virtual network that is isolated inside of vCenter

  I would like to set up a virtual network isolated within my vCenter environment, I have a domain controller and a few machines, I want them to be able to speak for them, but not to our network, is this possible?

  Can I simply create a vSwitch and attach it to any vmnic? Then add all the machines on the same workgroup?

  Yes it is possible.  Yes, just create a vSwitch and not to attach any /vmnics physical NIC and then add all the machines to the vSwitch.  Also, be sure to use a range of ip addresses that is completely different from your production environment.

  You can also use private VLANs.

  Please check the useful and accurate.

• Virtual network editor - virtual DC leak on network

  Hello

  I created a laboratory to test of windows server 2008 in vmware workstation 11. I put the custom virtual network adapter:

  

  I've got 2 VMs - windows server 2008 and win7. I tied VMnet2 both of these machines and created the field and join a windows 7 virtual computer to the domain. Great! but I have 1 problem. I put my IP to domain controller: 192.168.123.10

  But I can ping this address of the host (laptop) machine. is this normal? I thought about creating above network settings would completely isolate the physical network. Did I miss something or wrong configured network? I don't want the virtual network of VM fleeing somehow to the physical realm. I can't risk having 2 DCs on the network.

  

  so simple answer was watching me in the face. Just had to untick "connect an adapter to the virtual host on this network.

  For those looking to implement an isolated test lab windows domains, these are the settings you need.

  Thank you

• virtual network card to the physical network mapping and default loadbalancing

  What Virtual Machine virtual network card is map physical NIC.

  For example.

  lets assume Vswitch1 on host1 esx dedicated for the network of the virtual machine (port group) and it has 6 cards network linked to it (vmnic1, vmnic2, vmnic0, vmnic3)

  Load policy (default) Balancing - from the originating virtual port (it balances only outbound traffic through all the nic assigned to vswitch1 right?)

  ESXi host1 <-Vswitch1 (the VM network) <---(vmnic 0-vmnic 3)

  Lets assume that esxi hosting 6 virtual machines and each virtual machine has two network cards configured.  Through some documents, come out of that when the virtual machine is running, it gets connected to the ports of availabe on virtual swicth. say, I turn on the virtual machine in the order VM1, VM2... VM6.

  Vmname virtual adapter port on virtual switch1 Mapping of the physical network adapter                        

  VM1 eth0, eth1 1.2 which mappeed of the physical NIC to eth0, eth1?

  VM2            eth0,eth1                              3,4                                      ?

  VM3            eth0,eth1                              5,6                                      ?

  VM4            eth0,eth1                              7,8                                      ?

  VM5            eth0,eth1                              9,10                                    ?

  VM6            eth0,eth1                              11,12                                  ?

  Since we use load balancing based on the virtual port, can two virtual map of the same virtual machine are mapped to the two physical NETWORK card I want say eth0 VM1 is mapped to the (physical nic) VMNIC0, VM1 eth1 get connected VMNIC1 (physical nic).

  It would be great if you could explain how the virtual network adapters are mapped to the physical NIC Y at - it a command or a script to the list NIC(of all vms hosted on esxi) virtual NETWORK adapter mappings physical in detail.

  Is there a way to know what virtual NIC to connect to which physical NIC

  With the virtual NETWORK adapter, you hear the virtual card inside the VM? If if and when you use several VMNIC like you, there is no visibility in vCenter (usually vSwitches, we see with Distributed vSwitches).

  However, you can use the command-line ESXTOP tool in the view 'n', for the connection between the virtual machines and the outgoing vmnic.

• Best use of multiple NICS (collaborate with VIRTUAL networks or physcially separated)

  Set up my new production environment vSphere and trying to figure out the best way to set up the network.  I have pictures to illustrate, but the basic question is:

  1. use all NICS in a pool and VLANS to separate traffic - or -

  2 devote some physical nic to only certain things (VMotion, FT etc..)

  We use Dell R710 2 servers with 6 NIC of each.

  Our SAN is connected via zFCP iSCSI, see you in the group is therefore only for failover of emergency if environmental FC had to leave for some reason any.

  Please let me know which design you think would be the best.

  Hello

  Everyone says to separate the service of the VMnetwork console.  If I can separate the traffic of service with one console vlan why separate physically?  If something happens to the service console connection disconnects but my machines always communicate then I would have trouble.  Why not make sure that if the network paths are for machines that I can control the server VM?

  Your VMNetwork is one of network environments more hostile within the vNetwork as its arbitrariness and a point of attack if someone breaks into a virtual machine. If you have the virtualization management network attached to your VMNetwork is on, there is a VERY good chance that the pirate VM now will be used to launch an attack against the network of virtualization management. Given the current set of attacks there is a VERY good chance of success. For security reasons, you want your management network virtualization to be separated and protected by a firewall of any other physical and virtual network. Ideally on its own switches with output physical switch VLAN in use. However if you use VLAN physical switch then you put your trust in these spending patterns, so you want to increase your monitoring of these switches.

  Since the original post, I combined the iSCSI traffic because it is a failover of emergency only where my zFCP hardware has a problem.  The iSCSI link rarely go to never get used and I didn't spend 2 physical network cards to something that would almost never be used.

  You want to spend 2 links for iSCSI, if you still do not have a failover, you can the bandwidth and redundancy. Consider all the links of storage redundancy.

  Let me know what you think on the service console.

  When you use VLANS in the vNetwork you are automatically protected against most known layer 2 attacks, but in the pNetwork you are confident that your switch configurations you will protect. These configurations have been known to change and not necessarily for the better. Some say, it must break so for that to happen, but 1 problem of configuration and your SC is now attacked. Remember, once the virtualization management networks can be attacked they can probably be broken. I know a pen-Tester, which can do that in a very short time, and they will have your virtual environment.

  Protect the machine from service/management console, Client vSphere, vCenter servers as if they were gold, access to them implies access to almost everything. That's why VMware strongly recommends that you create another network of virtualization management a firewall of all systems on your system. That within this firewall that place you jump machines that run all vSphere SDK and vSphere client and that you use something like RDP to access these tools without their execution through your firewall. Make this thing increases the security of your global virtual environment of giant protecting your investment in the current batch of management network attacks. VLANs are not a security tool, they are a tool of separation of network based on the pNetwork is correctly configured, maintained and checked. VLAN security is based on the confidence in your pSwitches not something that is authoritative.

• Check Point virtual network adapter for SSL Network Extender

  I just downloaded an update recommended for Windows 10. After updating downlaoded, whenever I start my computer it say compatibility assistant this app is not working properly try to reinstall Check Point virtual network adapter for SSL Network Extender. Why do I get this notice? I have no problem getting on the internet. I have a modem and a router that work well with all my devices. I use an ethernet cable, nothing has changed in addition to the recommended update.

  I thought I would try devices and adapters Manager double click Network and looked for updates. Updated and now I don't get notification any longer.

• How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  I have a virtual network adapter that is created with Broadcom.

  This virtual interface named "BASP eCard" visible on the performance monitor in the category 'Rhythm Pipe' but not in the category "Network Interface".

  This is problematic because the Tx and Rx (bytes received/send in second) is available in "Network Interface" that show physical network cards only.

  Someone has an idea?

  Thank you

  Hate to tell you but PEAP is not supported by nature in windows XP. You must purchase and install a version of 3rd party drivers.

• Ea6400: virtual network

  Once more a question and then I think my router is perfect

  I have some IP cameras on my WiFi network.

  When I want to see them out I had to do a virtual network on my old router.

  When I go to Conectifity > Advanced routing

  I see that NAT and RIP

  Static routing is not the same as in the old router.

  But how I do on this one?

  Thanks for the thought.

  Hi taxikemperman. I agree with what proposes FurryNutz. You need to forward ports to access the cameras remotely. You can also register for any server domain so that you can easily access the camera outside your network. I would also say that you set a static IP address on each of the wireless camera, so you can correctly determine which cameras, you are trying to access.

• vWorkspace 8.0 | HyperV 2012 R2 | &lt; Unspecified &gt; virtual network name

• Software exists for the creation of a 'virtual' network card and going to all the traffic on the local network through a proxy server, then by this adapter?

  I can access net through LAN and my college requires a proxy for all access to the internet. If you want to use the internet, it is impossible to do not use a proxy. This is a problem for many programs that do not seem to allow you to enter the proxy settings.

  any software is to create a 'virtual' network adapter that will pass all traffic network (or any protocol x traffic) through the proxy?

  So I have do not need to enter the proxy anywhere... and I have normal internet access.
  What I saw is possible with OpenVPN, but it is a vpn service that I need .i just want to use the feature. In OpenVPN I just enter my proxy server in its framework and OpenVPN to connect to a VPN service and routes all traffic to the FAUCET adapter after which I don't need to set the proxy address anywhere... so my idea is how can I use only the last part that is routing all my LAN traffic to a virtual card.

  Support the LAN---> proxy---> virtual adapter--->, then software I access the net

  That's what I like to do...

  Although I am facing this problem on Windows 7, solutions for all operating systems are welcome.

  P.S: Proxifier is not my solution to not offer something like this.

• VIRTUAL network interface routed, is this possible?

  I have a 3560 which hangs a 6509. The next SVI s direct on the 3560:

  192.168.181.1(VLAN 192.168.180.1 (VLAN 180), 181), 192.168.182.1 (VLAN 182), 192.168.183.1 (VLAN 183), 192.168.184.1 (VLAN 183).

  I have the following routed interfaces between the 6509 (192.168.0.17/32 and the 3506 (192.168.0.18/32).)  Currently, I use a gateway of last resort to get the traffic off of the switch and a static route to send traffic to these IVS.

  I have a few VLANS that I use for vSpere and traffic of ESXI (239 (vMotion), 243 (Fault Tolerance), (250, iSCSIStorage), 254, ESXi), 255 network management).

  Is it possible to send these VIRTUAL networks through the routed interface?

  I have a few guests of ESXi requiring 254, 239 and 243 for vSphere features.

  Short answer is with the equipment you have not you cannot.

  What you can do is-

  (1) create a new vlan purely for the link between the switches and create an IVR for this vlan on each switch.

  The IPS for the Lass will be the IP addresses that you currently have on routed ports.

  (2) the link is a link to trunk and leave the new vlan and a VLAN that you want to extend for example. between the switches.

  The important thing here is to allow only on the trunk link the new vlan, and the VLAN that you extend.

  (3) the VLAN that you not extend ie. VLAN 180, 181 etc are not allowed on the trunk link and therefore will be always sent between switches across the new vlan because the Lass for this vlan have the IPs had initially allocated you to the ports of L3.

• PIX 515e, multiple VIRTUAL networks on a physical interface to DMZ

  We try to set up multiple VIRTUAL networks on a physical interface to the DMZ on a PIX 515e.

  The goal is to have logical subnets linked to our single, physical interface DMZ.

  Here's what I've tried so far without success:

  The switch

  -created the vlan 30

  -added switchports fa0/1 to 30 of vlan

  -attached host 192.168.100.1 in fa0/1

  -added switchport fa0/24 to the vlan 1 and vlan 30 with multimode

  -interface PIX DMZ connected to fa0/24 switchport

  -attached host to switchport fa0/10 172.16.1.55 (vlan 1)

  PIX:

  Auto interface ethernet2

  logical ethernet2 vlan30 interface

  nameif DMZ security50 ethernet2

  nameif vlan30 dmz2 security50

  address IP DMZ 172.16.1.254 255.255.255.0

  IP address dmz2 192.168.100.254 255.255.255.0

  Results:

  -172.16.1.55 has full connectivity to the PIX and beyond.

  -192.168.100.1 cannot ping the PIX to the 192.168.100.254 or anything else besides.

  Any help would be greatly appreciated. Also, I realize that I could buy a four port NIC and use the physical interfaces, but I can't get the approved purchase.

  Thank you

  Creation of VLANS on Ethernet1

  We want to create a new interface VLAN - VLAN30 and name DMZ2. Also affect the security level 50 in it.

  Step 1: Create a physical Interface:

  PIX (config) # interface ethernet1 vlan2 physical

  Step 2: Name the Interface and set the security level:

  PIX (config) # nameif ethernet1 inside the security100

  Step 3: Assign the IP address of the interface:

  PIX (config) # ip inside 192.168.1.1 address 255.255.255.0

  Step 4: Create the logical Interface:

  PIX (config) # interface ethernet1 vlan30 logical

  Step 5: Name of the Interface and set the security level:

  PIX (config) # nameif vlan30 DMZ2 security50

  Step 6: Assign IP address to the interface:

  IP pix (config) # DMZ2 192.168.100.254 255.255.255.0

  Step 7. Switch, set the port where from the inside, to the Isls or dot1q physical interface. Place the sheath in the native vlan2 as in step 1.

• Bind Virtual Network Interfaces to the physical Interfaces

  Good day to all.

  My situation is as such:
  

  I have a virtual machine running Red Hat Enterprise Linux as guest OS and my host machine is a laptop running Windows 8.1. Each operating system has two network interface cards. I want to place the virtual machine on the line between a router that would be on the left (side Intranet) firewall followed by Internet on the right (side of the internet). I hope there is an option that would allow me to effectively "bind" one of each virtual NETWORK adapter to each physical NETWORK adapter, so that when I place the machine host on the network line, it would be like the VM would be online also. So, basically I want to accomplish what is highlighted in RED in my small figure above.

  The full rectangle is the guest OS with its two network cards on each side, and the incomplete rectangle is the host device with its own two network cards on each side. I hope that someone could point me in the right direction, it would be greatly appreciated.

  VMware Player, "Configure the adapter" parameters are indeed not unique for each virtual interface. You use VMware Workstation to meet your requirement. For workstation, you can create two VMnets and link your two adapters to them, then connect your two cards in the comments to the VMnet respectively

• Easy way to export and restore the virtual network editor in 10 workstation

  I'm looking for an easy way back up and restore my settings of the virtual network Editor. I use Workstation 10.0.3 on Windows 7 64 bit and have several networks configured on different host machines. After Googling for the problem, I found the following:

  -on a Linux host, the settings are stored in/etc/vmware/networking. However, I am not able to find the file in Windows. Source: http://serverfault.com/questions/535193/vmware-workstation-how-to-automate-or-script-changes-to-the-virtual-network-co

  -on a Windows host, all parameters could be saved through export of certain keys in the registry. But these keys are at least partially unique on each host, and it would be a real pain to get the keys on each host individually. Source: Re: VMware WS configuration backup

  -vnetlib control should support a statement "-export" which creates a text file containing the necessary information. However if I try to run the command, as described in the link, no file is created on my machine. The command must be ' start/wait vnetlib.exe - export path_to_file' (I am running this command of in the workplace, of course installation directory). I also tried "vnetlib" - path_to_file to export, but that did not help either. I know that vnetlib works because I reinstalled successfully the vmx86 with vnetlib service - install. If also tried the vnetlib64.exe, but no luck. Source: Re: virtual network editor

  So is - someone of you knows how to solve my problem? I'm looking for a way to write a simple batch script that exports the settings without having to deal with the registry. My virtual network Editor loses its configuration from time to time and I don't want to set up everything by hand again.

  Thanks in advance.
