• "LAN Segment" option missing in the virtual network Editor

  I regularly use isolated networks to test things. With the help of my own DHCP / DNS /... Server for 'infrastructure'

  In 9.0.2 workstation there is an option "local network Segments. Miss me this option in 2013 of the workstation.

  Why this option has been removed? Or was it an oversight? Or should I add something to my configuration?

  Never mind.

  'LAN Segments' option is not displayed in the network Editor, but it IS displayed on the virtual network adapter settings page.

  I'm sorry.

• VMware Player 4.0 LAN segments

  I tried VMware Player 4.0 on Windows (Windows 7) and Linux (Ubuntu 10.04).

  One thing I noticed that a different Linux a Windows is that VMware Player on Windows has the choice to create and use the local network segment while in Linux, I can't find this option.

  Just a question here, is the segment LAN is a feature introduced in VMware Player 4.0? If so, how to enable it on Linux if possible? Any idea?

  I noticed that when I open a virtual machine on linux which has been previously configured to use the LAN segments on a windows computer that VMware Player DOES recognize the local Network Segment.  He didn't display the name of the local network segment or allow me to choose another LAN segment, but the comments seem to work on the local network as planned segment.  I don't have another computer virtual configured to use the local network segment.  So, I can't verify that they would be able to communicate effectively on the segment, but I suspect they would have.

  Why they support LAN segments and not only not wanted to give us a graphical interface to manage is beyond me.  But GUI seems to be pretty hit or miss on linux in general.

  Thus, a possible solution is just manually edit the file ".vmx" to set up so that it uses a local network segment.

  (1) turn the VM guest that you want to change and to use a local Network Segment.

  (2) open ' / home/vmware //.vmx "with a text editor.

  (3) look for a line similar to:

  ethernet0. ConnectionType = "hostonly".

  (4) change the line as follows:

  ethernet0. ConnectionType = "Charlotte".

  (5) add a line similar to the following line at the end of the vmx file (this identifies the LAN segment to which will connect the VM):

  ethernet0.pvnID = ' 52 52 64 84 ea 7f 81 13 - df this 81 3 c 59 5b b7 e5.

  (6) to save your changes, close the text editor, and open the settings of computer virtual of the guest in VMware Player PC to check the NIC is plugged into a "LAN" Segment declarations

  (7) make the same changes on other virtual machines that you want to be on the same LAN segment.

  NOTE: The path identified in step 2 can be different on your system.  You can find the path by using VMware Player by going to the settings of the virtual machine in the virtual machine, selecting the 'Options' tab and looking at the "Working Directory" in the "General" settings  You should find the ".vmx" for the virtual machine file to this place.

  I hope this helps.

• How to connect a LAN Segment to the network host Workstation 7

  Hi all.

  This can be a really newbie question, but I'm quite a novice on vmware

  I have set up a team in VMWare Workstation 7 with a few machines virtual all assigned to a single LAN Segment. Everything works fine, but now I need to have internet access in my virtual machines. How to configure the local network segment to see my host network, so I can internet ping?

  Thank you very much!

  OK - see here - I have matched to your vmx file so that all the entries of ethernet0 appear in a row.

  That's what you have now:

  ethernet0. AddressType = 'generated '.

  ethernet0. ConnectionType = "Charlotte".

  ethernet0.generatedAddress = "00: 0C: 29:c3:36:10.

  ethernet0.generatedAddressOffset = '0 '.

  ethernet0.pciSlotNumber = "33".

  ethernet0. Present = 'TRUE '.

  ethernet0.pvnID = ' 52 4 c 5th 98 70 6 82 a-1 b - 0f 97 5 m 76 2 8 a 85 eb ".

  ethernet0.virtualDev = "e1000".

  ethernet0.wakeOnPcktRcv = "FALSE".

  Then, I list all the settings that you should NOT touch:

  ethernet0. AddressType

  ethernet0.generatedAddress

  ethernet0.generatedAddressOffset

  ethernet0.pciSlotNumber

  ethernet0. Now

  ethernet0.startConnected

  ethernet0.virtualDev

  ethernet0.wakeOnPcktRcv

  Regardless of the settings of they - leave it alone - don't change to it for this task. After that only these two lines are left:

  ethernet0. ConnectionType = "Charlotte".

  ethernet0.pvnID = ' 52 4 c 5th 98 70 6 82 a-1 b - 0f 97 5 m 76 2 8 a 85 eb ".

  These two are those who configure the local network segment.

  Remove them and replace them with this single line

  ethernet0. ConnectionType = "nat".

  In case you want to break up the team to remove this line

  inVMTeam = 'TRUE '.

  and delete the *.vmxf file in the same directory.

• 1 traffic lane between hub router VPN 3 K

  (1) network private VPN concentrator: 10.0.5.96/27

  (2) private network router: 192.168.1.0/24

  I have network list define the VPN concentrator:

  10.0.5.96/0.0.0.31 under local area network

  192.168.1.0/0.0.0.255 remote subnet

  I defined the crypto on router access list:

  access-list 101 permit ip 192.168.1.0 0.0.0.255 10.0.5.96 0.0.0.31

  The debug version of the router, I can see that the IPSec Security Association is being created. When I'm running cryptographic engine connection active, there are packets sent encrpted but no package that is decrypted. What would be wrong on my setup?

  Hello

  After the tunnel is established, try to send a portion of the traffic through the tunnel watching the monitor on the VPN3000 sessions to see if you have packages that RX is growing or not.

  If so, then make sure that the host to which you are trying to access is powered and knows that he must send the packet to the VPN3000 for the 192.168.1.x/24.

  If not, then see if the VPN3000 sits behind a firewall that blocks protocol 50 (ESP).

  And what happens if you generate the traffic behind the VPN3000.

  Kind regards

• Adding a switch to an existing wired LAN House

  I have a wired LAN House that needs to be expanded.  I have a Linksys BEFSR41 Cable/DSL router that is currently full.  I need to add more than 2 devices.  I recently bought a workgroup EZXS88W switch.  What I had thought to do running cable line from the router to the switch and everything else after you have connected to the switch.

  I know zip about how to set this up, so please help.

  Well, connect a cable from the router's Lan to the Lan port of the switch (for example Port 1 of the router to port 1 of the switch).

• Same MAC address LAN different segment, different ESX, different groupings? questions?

  Hello

  I have a question reguardning assign the same address MAC 2 mV.

  A quick overview of our environment is:

  1 vCenter

  2 different groups

  Virtual machines are not in the same LAN segment.

  We have cloned a VM to group A to group B. The license for the application is linked to the MAC address of the virtual machine. However, with a few changes to the .vmx file we have changed the

  static ethernetX.addresstype

  ethernetX.address for the MAC, we wanted to

  added the ethernet.checkMACAddress = "false".

  While the two virtual machines have the same MAC, VMS are production and VM B are development.

  It works very well and we can turn on the virtual machine in Group B and both A and B works very well, the application works fine in the two clusters. BUT here's my question.

  vCenter keeps track of MAC addresses and VM b it gives an error stating that "the static method address MAC attributed to VM B, is in conflict with the VM A MAC» Then can there be a problem for us? We can be right now two virtual machines are in place and working well just. And the application also works very well at the time of the cluster. The only one complaining about this is vCenter.

  Someone has the right answer for me?

  Since you have no problems of network just ignore this warning.

• LAN with VMWare Workstation 7 segments

  Hello

  someone has already tried the "LAN Segments" feature of VMWare Workstation 7?

  I have the following configuration:

  -1 team

  -VM´s 4

  -3 LAN segments

  2 machines are configured to be together in a local Network Segment (LAN 2) with the following parameters:

  -The name "LAN 2.

  -Bandwidth: "leased line T1 (1.544 Mbit/s)

  -1544 kbit/s

  -0,0% packet loss

  Although I configured this team I always > connection 100 Mbps between these two VM´s. I´ve tried transferring a files 35 MB of a VM to another using a fileshare.

  Someone at - there experience this problem in VM7? Do anyone know if this is a known bug?

  Ah--along the way. I use build 203739

  Thanks in advance,

  Jan

  You turn on the team through the power team orders or you turn on the VMs system individually?  There is a known bug where network segment settings do not work for the latter.

• Very strange Vista problem when behind a switch

  I bought the router WRT610N along a LINKSYS EG008W 10/100/1000Mbps Gigabit Workgroup Switch. In my small office (4 closed offices and an area central + kitchen + room + storage + a bowl of chocolate for my pregnant wife), we were using our ISP (Bell) modem/router (Wi - Fi + 4 ports RJ-45) with switch 8 old ports. There are 3 Mackintosh a XP and a Vista workstations and a D - Link DNS-323 NAS on the local network, + XP/Vista/Mac laptop wireless now and then. I wanted to update our stuff for a flow rate of localized Gigabyte (still looking autour to build a Xeon server + file server), with Wireless N Dual-Band, and the following configuration has worked right away without installing anything same software-wise, nor the need to reset - restart a computer or device: all records shared Internet connection was available immediately which was very satisfying. I even bought Cisco Network Magic Pro 5.5 and I'm glad I did, this is a really well done and intuitive graphic interface to manage small business networks (one license for PC stations up to 8 + 8 Mac stations), if not the best out there for its target market niche and prices vary.

  However, there is a confused about Vista glitch: I have to fix directly on one of the ports on the WRT610N, it won't work if I try behind a switch box (although it works for all other operating systems), using the following network configuration:

  1. all the workstations are connected to the switch, focused on one of the ports of WRT610N
  2. The Internet WRT610N port Bell's DSL modem
  3. SIN D - Link DNS - 323 and the port 3 WRT610N
  4. EG008W Switch 4 port WRT610N 1 port
  5. Workstation to the switch EG008W 2 Vista port
  6. Workstation XP and switch EG008W 3 port
  7. Workstations Mac to switch EG008W ports 1, 5, and 6

  From the XP desktop, I see Macs and access the NAS. From a Mac, I can see + access the XP and the NAS. Vista station connects any behind the switch EG008W: I * must * plug into the router, WRT610N, something I don't want to because the switch is there to serve as a wall mounted RJ45 plugs into each office (where the Mac XP and Vista workstations are located)... Any help or link to a relevant reference would be greatly appreciated.

  Kevj, thanks for answer you, I came here to close the topic because I put the finger on the problem and it is resolved: the problem lies elsewhere, it is not the calbling or some other hardware problem. I have replace the Vista box by a mobile XP, using the same wiring right and everything worked well, he wasn't a wiring problem... Note that the workstation is a Dell Studio which comes with a Realteck Gigabit controller box (so I guess that many other models/brands also provide this same controller, which means that many other users can know this problem).

  Here's what I did:

  • I got rid of Vista by installing Windows 7 and everything worked fine!
  • I then published an update of Windows from the Microsoft site, which offered a patch for the familly Realteck GBE (among other patches) controller
  • After restarting the computer, the network was not accessible more while the Win7 box is behind the Swithcher: it behaved exactly as when it was Vista (indicating that the adapter was unplugged when behind the selector and then giving access while behind router WRT)!
  • So I restored the last just restore point prior to the update of the controller and got everything back to normal; I then did another session of MS Windows Update without the Realteck driver patch, and everything worked well.

  Conclusion: DO NOT update your controller driver Realteck GBE from Microsoft, whether for Vista or Windows 7, it has a bug which takes place whenever your Vista/Win7 box is behind a DMZ sub-segment of LAN using a blender (switch-router-router/DSL-ISP).

  Note: the WRT610N works like a charm! It is plugged with a RAID0 of DNS-323 1 TB NAS, one 8-port Gigabit switch power supply 3 macs, 1 XP and 1 Windows 7, Wi - FI works well enough (G mode, while the band n is open - I don't have a camera of 5 GHz yet so I can't say for this FREQUENCY range) and I left the own DSL access available Point. Which means that there are 3 Access Points: one directly on the DSL router that leaves the LAN in a DMZ (cannot be seen or accessed from the mobile) and 2 more on the WRT610N dual band access not only to the Internet but also for shared resources). Blue color for the port connected to the dwitcher, which means a Gigabit local LAN, and green port for the DNS-323 whitch works to 100 MB (unfortunately they still do not have a Gigabit NAS). I am very happy with the product, more when combined with Network Magic Pro.

• LAN failover

  The only information I get on Cisco, it's that you can NOT use a crossover cable. The only possible connection type is a hub or switch. Can someone, please, tell me why not a crossover?

  It is not a restriction as such. As some of you know, his works. The current design assumes that there is a switch/hub in the meantime, this shift can identify when an interface has failed and act accordingly.

  For example, if the failover for the PIX_a lan interface has failed, then PIX - b can take more active, but cannot do so if they are connect

  using crossover cable as PIX - b will see its interface was not as well. Most likely, the client will use a switch/hub

  in the meantime to increase the distance between the 2 PIX when running on LAN fover.

  Hope this helps,

• PoE to power a switch

  Does anyone know of an Ethernet hub or switch that can be powered from Power Over Ethernet?  I have a location without electricity but with an Ethernet jack.  This would allow me to extend the network there without having to invest in the walls of the electrician and opening etc.

  Thank you.

  There are switches that can provide Poe or be powered by PoE equipment (such as Netgear and TP-Link) network suppliers. It is also possible to use a separate PoE injector for the provision. For switches/routers without possibility to be powered directly by PoE, a PoE splitter can offer an alternative solution. There are some limits of voltage and current (and temperature) that must be respected. In addition, always check the construction and electrical instructions for your country.

• Equium U400-145: Wireless LAN cannot be disabled

  Hello

  I can't turn off the LAN wireless with the switch or the Fn + F8 key. Although both are the indicator wireless LAN off (light in the front of the machine) the wireless LAN remains active.

  I tried to reinstall WLAN Driver and installed the last package of added value.

  Hello

  This seems odd, that if you can not turn it off with the wlan switch, it may be a malfunction of the equipment. Have you tried to restore factory settings? Please, do it. If she doesn't fix it, there is hardware problem. I have never met such problems.

• Can't access mailserver when the LAN!

  Hello.

  I just install an Apple Airport Extreme (model Tower) as DHCP incoming WAN and one LAN out to a switch for the rest of the House/LAN connection.

  But after the addition of the AE to my network, that I am more able to access my Synology mail server messaging, when I am connected to the local network. But if I use my iPhone on LTE, there is no problem!

  I used the router configuration configuration option on my DS-214se, to configure the DS with the AE.

  Someone has any ideas why this happened? I think that I have heard something about the closure of NAT, but I'm

  not sure if this is the problem and I do not see any where to set Nat Loopback on EI.

  Kind regards

  Stone.

  I just install an Apple Airport Extreme (model Tower) as DHCP incoming WAN and one LAN out to a switch for the rest of the House/LAN connection.

  By "DHCP" do you mean you have set up the AirPort Extreme to use router Mode = DHCP only? What is the brand and model of the device that is connected to the WAN port on the extreme?
