• Laboratory of network of production using rdp Server 2 NICs (1 connected to prod vswitch and 1 single vswitch)

  Hi all

  I have a copy of my DC prod and a few servers on the host esx5 I created a single vswitch (no assigned network card). Besides all the vms on the isolated vswitch laboratory has no (empty) assigned default gateway ip address. Security measure. Let me explain briefly... everything is good so far... .but to access virtual machines on isolated vswitch, I need to connect to vcenter console to virtual machines. It's ok but very slow heavy and slow ...

  I thought to create that a virtual machine allows to call him my rdp Server I'll rdp on prod, then this machine virtual, I'll rdp on vms on isolated network lab. configuration of the server rdp as follows.

  I assigned 2 network cards to the rdp Server (to connect to prod vswitch network and another vswitch isolated), now my question is this secure?  which means in any way I want my isolated vms on vswitch lab test connect to servers of prod, this woulkd be a nightmere. As I am unable to ping test prod servers from computers virtual lab, and I wasn't expecting to. remember as a precautionary measure, I do not use a gatewate desktop virtual lab and I can only ping the server rdp... .so far so good

  Please let me know thoughts or maybe someone has put in place in the past...

  Thank you

  Yes it's course - internal traffic only network is isolated from the network of productin you - that traffic will come out is if place a router between the two networks

• External network configuration

  I'm creating an external network for my vCloud assessment.  Only, I intend to have one.  When creating, there is the page 'configure the external network.  You can add lines to the configuration, each apparently being an external subnet that you connected to.  I have a few questions.

  (1) when he says 'Add the subnet' on the wizard, and there ask for the gateway and mask, we're talking the subnet external, correct?

  (2) why can I add several lines?  It seems, in particular, given that my group of underlying port is a VLAN / single subnet, that it would be unwise to add more than a single subnet here.  Under what circumstances I would add more than one row of subnet in this configuration?

  Thank you

  So, when you add an external network, you choose a group of ports in vSphere.

  1. you give the information required to configure the NIC cards to be attached to this network, then Yes... all that is on the same physical network real.

  2. some companies want to only allocate specific subsets... maybe the initial set of IP addresses are free, because it is shared with the physical realm.

  Later, maybe you release more... but this isn't a continuous block.  You can then add a second beach.

  It is for the flexibility, nothing more.

• Several physical NIC cards connected to vSwitch / Port Group

  Hello

  I have several physical NETWORK adapter on a host connected to a single vSwitch / port group, does this mean that the speed of the network is shared by all of the physical NIC, or I have to do something special to enable this feature?

  Please see attached .jpg

  Thanks in advance.

  If all of your network adapters is active in the nic teaming configuration, you must have a physical switch that supports the aggregation of links and you must configure it. The ESX itself does not have this kind of work.

  Actually is a bad idea to let all NICs connected without having to configure the nic teaming (1 active and others waiting for failover) or without going through the aggregation of links.

• Not enough external IP for external network access

  Hello

  I am a newcomer to Lab Manager and my Department has not enough IPs to work until several virtual machines on LabManager. If we think about the use of private network as 192.168.x.x address to create a configuration and we checked which is supported using the virtual network model. But the question is whether I would like that all the virtual machines in this network is able to access the external network vLabManager will try once again each of the virtual machines assign an external IP address that we are lack of.

  So my question is the gateway for network in a configuration can be used as a router a provide NAT to allow virtual machines in a network deprived of access to external sites? Or other solutions better to solve our problem of IP all allow the virtual machines to access the external network?

  Thank you.

  The previous reviewer mentioned that NATing is supported (VMware calls this "fence"). If you are exposing ALL the machines in your configuration on their own fenced address, you will not get IP address consumption savings you want. To reduce the number of IP addresses externally exposed in a NAT configuration, you should design your configuration so that only a single IP address is exposed through the fence. A similar debate along these lines took place here: http://communities.vmware.com/message/1245907#1245907

  In a configuration of 4 machine you can put 4 machines on a network "dark." One of these devices will have to be multihomed on two networks. The hosted machine multi risk exposing his unique IP address either on the network or through a closed network directly. In both cases, only a single address would be exposed on your external network and you can use it as a gateway into the 3 other machines.

  Would be nice if the router fence could be directly configured to support some simple flavor of tunneling. Currently this capability is not there.

• Assignment of IP with vCAC external network profile

  I joined vCAC and NSX, and note that the Service Edge router that gets deployed on a blueprint multi-machine receives 2 IP addresses on its unique "uplink" profile external network interface.  Here is my setup and what is happening.  Any help to understand why this would be useful.  Not a huge deal because it is a learning laboratory, but when I go to implement it in a production environment, I need to know if this is expected behavior, or if something is wrong because it effectively reduces the number of possible networks to deploy-able by half.  Again, not a big problem as this "transport network" (the section between the Edge Gateway manually deployed and dynamic Service Edge routers) will exist entirely in the vSphere environment and can be as big as a class A network, if necessary, it is however a huge waste of space IP I want to solve it if possible.

  Topology:

  I have a NSX Edge and the virtual wire (switch NSX L2) already deployed in the environment.  Within vCAC I have:

  -a reserve related to the dvPortGroup created by the NSX L2 switch

  -an external network profile that is used to configure the port to uplink of dynamically deployed NSX routers edge of Service to connect to the LAN segment between the dynamic ESR and the switch of NSX Edge/L2, already deployed

  -a profile of NAT network 1 number which is used to configure the virtual machines deployed from vCAC plans

  -a vSphere vCAC VM blueprint pointing to a snapshot of a virtual computer within the environment vSphere (linked clone deployment)

  -a plan of multi-machine vCAC which contains the above plan and assigns a network interface to the virtual machine and using the profile of network NAT 1 to configure the IP settings on the virtual machine.  MM master plan contains only a single VM in order to test the dynamic creation of network and IP assignment features/integration between vCAC and NSX.

  Topology resulting, once the virtual computer is deployed:

  Edge (deployed manually) NSX gateway

  v

  v

  NSX L2 Switch/Virtual Wire (deployed manually

  v

  v

  NSX edge router Service (deployed as part of the deployment of the vCAC action plan)

  v

  v

  VM (deployed as part of the deployment of the vCAC action plan)

  In theory what needs to happen is that when I ask a resource of the Architecture SDSE MM:

  1. the ESR is deployed with 2 interfaces: 1 for the external network configured with an IP address available on the corresponding subnet and 1 for internal NAT network configured with the IP address of the default gateway is configured in the profile of NAT network.

  2 NAT rules and treatment of traffic are automatically configured in the ESR

  3. the virtual computer is deployed and configured with a NETWORK adapter with the configurations appropriate IP such as specified in the profile of NAT network.

  
  What is actually happening:
  1. the ESR gets deployed with 2 network cards; 1 NETWORK card for uplink to the external network, which gets 2 IP addresses on the subnet (instead of 1) 13 and 1 NIC for the default gateway of the NAT had network configured with the IP address of the NAT network default gateway.  Steps 2 and 3 still occur.

  Hi Jeremy,.

  It is the expected behavior. If you deploy an edge manually, you will be asked for a 'IP management', and then an IP address for the use of the uplink. It is the second IP source address. If you were to use a NAT, you get an additional IP address for each VM on the NAT's segment.

  See you soon,.

• Why must id VLAN unique for each external network?

  Sometimes we have several public networks with the same VLAN, but in this case, we could not add them as external network to vCloud Director, he complains that the VLAN ID has been used, then assign a VLAN ID for each public network. Could someone explain to me why a unique id of VLAN is needed here?

  Thank you!

  If they are the same vLAN on the same Switch, they are actually exactly the same from the point of view of the vCloud Director.

  The alternative is to see if the superposition of external networks allows it works (Admin > General).

• regarding the connection of the virtual machine to the external network

  Hi all

  I'm new to vmware and I have two virtual machines with windows operating system 7. How to connect to the external network?
  can I assign a NATed IP to them?

  If the need to talk about virtual computer internally, you can add all the VM in the same VSS(vswitch 1) at the same port group Network2 VLAN40. for virtual machines on that VLAN can communicate among themselves without problem and configure all virtual machines with IPs in VLAN40. no need for an another vs.

  For internet access, first check with your network administrator, if the VLAN has a routing or this VLAN has access to the DNS server that provide internet or the proxy server for internet access. He will confirm. or you can also check if this virtual machine are able to ping your DNS server or proxy servers. If its power of ping so it has access to this network. Configure the virtual machines that you configure a physical computer for internet access.

  If the VLAN has access to the internet, even that you configure the physical server with connection DNS and proxy for internet access only the configuraiton even here too in the virtual machine.

• vCloud Director network configuration external network

  Hi all! For the configuration of external network within vCloud Director, I have a vDS configured with several groups of ports.  Each port group has a tag of vlan specific and no trunking.  My question is when I create the external network I can use the port group specific enumerated or what I need to set up a completely separate portgroup for this?  Also, if I can you my existing port groups that are specifically for each company in our environment, when I continue to configure the external network and click on finish, or if it cause a breakdown to the virtual machines currently in this group of port?  Thanks in advance for all help!

  If you use directly connect external Org network, then the existing portgroup will work.  If you use an external org routed network, then edge will be created using the portgroup you specified for the external network and creating a new portgroup for the routed network ext org portion.

• When you connect 1 or several external USB drives, why is the letter a * shoot?

  When you connect 1 or several external USB drives, why is the letter a * shoot? Referencing external drives through library (Windows V7) becomes a really shiny, totally useless feature without consistency of drive letter. Or unnecessary to be a design goal? I almost had it still works but who finally to 3 minutes). What it will take to make useful new features?

  Windows assigns the first available on the first hard drive connected and one drive letter to another and so on.  Always has, always will. What will help sometimes (but), is to open disk from an elevated command prompt management and adversely affect permanent a letter from your external drive which is much higher than the letters in use.  This will often allow the will to keep a letter.

• Configure the public traffic network IP inside the internal network itself and not to the external network

  A server is now accessible from external network access using the IP and port in browser below http
  http://x.x.x.x:8080

  For the same, we have configured (static NAT) port forwarding in cisco security 1905.

  The application is also accessible via IP and the internal network port internal (ie. http://y.y.y.y:8080)

  Is there a way I can configure my 1905 Cisco as well as internal network (ie. machine B) I can access the application using the IP and the public port and not with the IP address internal? From now on, I'm not able to do the same.

  The current configurations are as follows:
  access-list 1 permit y.y.y.0 0.0.0.255
  IP nat inside source list 1 interface GigabitEthernet0/0 overload
  IP nat inside source tcp static y.y.y.y 8080 interface GigabitEthernet0/0 8080

• I use Windows 7 and I am not able to print several different images on a single page.

  When I try to print photos from the 'My pictures' library, I use the following steps:

  1. turn the photo highlight

  2. click on 'print '.

  3. in the window that says: "How do you want to print your photos? I choose the number of photos I want per page, for example 3 x 5.

  4. when I try to add a picture DIFFERENT from my library so that I can print several different photos on this page of photos of 3 x 5, it simply replaces the previous photo. How can I get there?

  Thank you.

  Original title: I use Windows 7 and I am not able to print several different images on a single page. The answer posted here from 8/11 includes a link that does not work.

  Hello

  Welcome to the community of Microsoft and thanks for posting the question. I've surely you will help find a solution on the issue.

  What program you want to use?

  We will try to print in a different way and check.
   
  Open Paint and then do a collage of different photos then save it then open it in their program and print.
   

  To print the image in Microsoft Paint, steps to follow:

  a. Click Start, in the search box, type in the paint.

  b. open the document you want to print.

  c. select print and check.
