• 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,.

• 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

• 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.

• Change the IP address in the user profile of the Network Configuration?

  I added some users on the network configuration in order to change the ip address when they are in the other site, but in Windows 7 it is inviting to enter the user name and password, if a single user, enter the name password it will allow them to change the ip address how to change so that the user is able to change your ip without asking for a password and username?  How can I solve it... Thanks in advance.

  Nerdcat

  Address you internal IP is defined by the router or the ISP based on your configuration.  If you try to change the internal IP address using "static IP" you shouldn't have to enter a user name and password so that it is in configuration and fixed like that.

  You cannot change the external IP provided by your ISP it however.

• Get a next available external network IP

  Hello

  I am trying to automate the deployment of nested environments that require external network connections. I'm looking for a way to determine the next free IP available from a given external networks IP pool. I can get the list of IP addresses in the pool, the number used and total number total free but have been unable to find a method to show what is free then.

  There must be a way to get this information that the deployment of a new edge on an external network takes the next free IP available.

• Several external networks on a single vswitch

  I am trying to understand (among others) if I need more a vmkernel on the same vswitch. It is related to a question I posted last week, but I understood some things since. Here is the configuration (slightly reduced for reasons of this discussion).

  2 vSphere 5.5 hosts, each with:

  1 vmnic connected to external switch capable of trunk ports (vSwitch0); It is currently the management network

  1 vmnic connected to the switch for vmotion (vSwitch1)

  1 vmnic connected via switch private iscsi array; the private switch VLANs separated for iscsi (vSwitch2)

  VMotion and iscsi works very well, so I am concerned mainly with the external networking. Currently, all virtual machines are on VLAN not signposted. We will change to 2 VLAN tagged on different subnets - 10.1.10.x and 10.2.20.x. The VMs will have to talk to each other so that on different hosts. So, does that mean that I need 2 vmkernels on vSwitch0 - one for the 10.1 subnet and one for subnet 10.2? Then the Group at a port by vmkernel and matched vlan id for group of ports and vmkernel?

  OR

  I really only need a single vmkernel on vSwitch0 with 2 groups of different ports for the different VLANS? IE, VMs with different networks than network mgmt will be able to communicate through the external switch to virtual machines on other host?

  Also, I expect that external ports must be set to allow 1 marked and tagged 10 labeled 20 - is that correct?

  So, does that mean that I need 2 vmkernels on vSwitch0 - one for the 10.1 subnet and one for subnet 10.2? Then the Group at a port by vmkernel and matched vlan id for group of ports and vmkernel?

  No.... you need not multiple VMkernel can use different virtual machine networks in your ESXi host.

  I really only need a single vmkernel on vSwitch0 with 2 groups of different ports for the different VLANS? IE, VMs with different networks than network mgmt will be able to communicate through the external switch to virtual machines on other host?

  Yes, just use the existing VMkernel management interface and create two groups of ports, one for each VIRTUAL local area network. Yes, VMs of different VLAN in network management will be able to communicate, BUT your physical switch must be configured to allow traffic from multiple VLANs.

  Also, I expect that external ports must be set to allow 1 marked and tagged 10 labeled 20 - is that correct?

  It should work.

• vShield Networking - configure NAT rules directly in vShield Mnager

  Hello

  I tried to configure a NAT rule to enable access for external network users that is not routable vsphere Client i.e. the plugin for vShield manager to the internal network. I have found no documentation for this. Now, if I place a load balancer it automatically creates a NAT rule. Don't know why I can't do the same thing using NAT exclusively. Someone out there who has done the basic NAT using vShield Edge between 2 distinct networks (L2)?

  I realized what was wrint with my setup. The EDGE is deployed in a lab where we have the internal network, access to the outside, but not the reverse. Thus, we had another gateway on the virtual machine and therefore return traffic never returned to the edge gateway. If it was a problem with my knowledge of NAT.

• Unable to connect to the external network

• 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.

  Enter the user name: ops Sham $
  Enter the password:
  Connected to:

  Because, despite the "ops$"... ops$ feint isn't an authenticated OS account. This is a database of authenticated account. It's only a database of authenticated account because you gave it a password. From your previous post to Justin:

  -quote from the previous post to start-

  SQL > CREATE USER ops$ sham IDENTIFIED EXTERNALLY.
  Created by the user.
  -suspend - quote

  OK, at this point, you have an authenticated os account "$ops Sham".

  -quote to continue-
  SQL > GRANT CONNECT TO the Sham ops$;
  Grant succeeded.
  -suspend - quote

  Now, the operating system account 'sham' should be able to connect with a simple "sqlplus / '.

  -quote to continue-
  SQL > grant dba to simulacrum of ops$;
  Grant succeeded.
  -suspend - quote

  Now, anyone who uses the operating system account 'sham' can connect without a password and have all the privileges listed in the role of "dba".

  -quote to continue-
  SQL > alter the simulacrum of $ ops user identified by shamos.
  Modified user.
  -end quote-

  But now change you your account "$ops Sham" and gave it a password. OPS$ feint is therefore more than a bone authenticated account. It is now a database authenticate the account, but with a rather misleading name. At this point, if you are trying to connect as "sham of the ops$", you will need to provide a password.

  I want to know the difference why this sqlplus command / error display

  Because you're tying to use authentication with an operating system account that is not an operating system os authenticated account in the database. Put "ops$" on the name of the account is NOT what makes an authenticated os account. What makes authenticated os sets the account as "identified on the outside. If you create as 'identified by somepassword', OR if you CHANGE to 'identified by somepassword' then it is NOT authenticated os.

• Question simple re: network configuration

  I'm trying the VMWare Player Beta 3 from the image converted to MS Virtual PC from VMWare by VMWare converter.

  Works very well so far, but I can not configure the network.  My host is a XP/sp3 running and the virtual XP machine.  I'm temporarily without a router, so my ethernet card is directly connected to my DSL modem.  I put it to bridged vmnetcfg.exe and used (which must manually extracted installation files) to check that it automatically connected to the correct LAN card.

  Yet, nothing works.  ipconfig in virtualization shows nothing connected, nothing can be crazy, etc.

  What Miss me?  The help files are not clear on how I need Windows upward in the host and the VM.  Things will be clearer when I'm settled and I have a good router, but until then, any suggestions?  There is advantage to try NAT?

  Yes, NAT would be a better choice for the moment.  Most cable ISPS provide only a public IP address with your account and your host (most likely) he uses.  Your guest has a different MAC address and is considered to be another computer.  When you select bridged mode, the prompt is considered by the external network as a separate computer... and so your ISP does not and will not give him an IP address.

• 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.
