Two VLANs in the same network bubble?

Hi all!

I do not know very well of networking, and don't know my VMware network guy, so I hope that someone here might be able to answer my question. Thank you!

I'm testing the conversion of some of our production servers. Since they have the same name, they are all in a bubble of network on the same host. So I have a vSwitch called "Bubble Network Test" which has several virtual machines, but who doesn't have an uplink (no associated physical map). So far, this has worked very well. So that users to test, I also have two XP machines to also live in this bubble. However, we will have performance issues. In our test of D/R one a few months ago, we found that the application performed very bad when the customer was in the same VLAN as the server; change the client to a VLAN different fixed performance.

So, I would do it here in the hope that it will improve performance. However, I do not know how to do it. Can anyone offer any tips/advice on how to have more than one VLAN in the same network bubble? I have to make two vSwitches and then connect them somehow?

Thank you!

As long as you stay internal to the ESX Server then Yes you will need virtual switches - you will have then a virtual machine that will span two switches, acting as a router routing traffic between VLANS.

  • Two routers on the same network wireless?

    Last night I bought a WRT160N, to replace my old WRT54G. The 160N is now in my room, connected to a cable modem. The 160N ethernet ports, I have a cable that goes from my room, through my attic and comes out in my living room. In my living room, I'm willing to hang the cable that comes from my 160N to my WRT54G. Then ports ethernet on my WRT54G, I want to connect my Playstation 3 and Xbox 360. I have this connected physically this way, but the PS3 does not connect to the internet through this wired connection. (Have not tried the Xbox 360)

    Basically, I'm eager to share the connection from my wall between my PS3 and the Xbox 360 so that they both have wired connections. Also, I would like to know if I can have both routers broadcast wireless on the same channel, so they appear as two wireless networks. Is this possible?

    Looks like you will get almost everything on your wish list.  You can have two wireless routers, and they can both diffuse.  Normally, you would use the same SSID for both routers, but different channels.  Your wireless computer automatically selects the channel harder, so you can "roam" between two routers.  However, this "roaming" is not as good as with cell phones, then you should only "roam" when your wireless connection is idle (i.e. not an active download).

  • Advantages and disadvantages of the use of the same network card to the network management and production (all my virtual machines) VLAN?

    Hello

    I have an ESXi. The management network and the virtual machines vlan through the same network adapter.

    What the disadvantages are to do?

    Can you help me please?

    Thank you in advance,

    Kind regards

    Well well, in this case. This is a perfect case of SPOF, try to reach NIC teaming to avoid this.

    At least two cards physical network is necessary in your hardware ESXi host to do.

  • BEFSR81 with WRT54GS to the same network?

    I currently have a LinkSys BEFSR81 connected to a cable modem that I need at least 6 ports wired to my home network.  I also have a WRT54GS which is currently unused, but I want to add to the network so I can have both wireless connectivity.

    Assuming that it is possible, what is the best way to combine the two units in the same network?  The simply connectable WRT54GS downstream of the BEFSR81 via one of the ports open?  I guess I'll have to change the IP address of the wireless device for individually accessible for configuration, check status, etc.  All the other things I have to do?

    Please notify / thank you!

    I found the solution in a previous post, sort of.  Here's what worked for me:

    (1) connect direct PC to WRT54GS

    (2) turn off DHCP and change the WRT54GS IP to 192.168.1.2 (192.168.1.1 for the 'master' BEFSR81 vs).

    (3) save changes

    4) activate wireless, configure security, get access, etc. on the WRT54GS code

    (5) save changes

    (6) re - connect the PC to the original port BEFSR81

    (7) connect the ethernet on BEFSR81 port to a port ethernet on the WRT54GS (NOT the Internet port)

    (8) to enter the code in the WiFi device and make the connection...

  • Two Macs can connect to a URL, another on the same network may not

    So far, I can connect this behavior to a unique URL only - but of course, it's an I need to get in order to save some software on this particular machine.

    I emptied the cache, flushed the DNS cache and checked that I use valid DNS servers. It isn't Safari, chrome this brings. Two Macs reached the URL without any problem, but this new model Mac Pro simply will not reach it and traceroute expires after a few jumps. All three machines are on the same network, all three use the same DNS servers. I rebooted several times.

    All three Mac running the latest El Capitan. The two reach the URL are a MacBook Pro and a Mac Mini Server.

    I'm puzzled.

    Please note that a traceroute on all three machines reveals the slowdown even at the same jump in the chain, but only the Mac Pro seems to have trouble with it.

  • Two interfaces WAN ISP in the same network

    Hello world

    I am faced with a really simple but delicate scenario. My ISP gives me IP addresses public 2, both in the same network. They also gave me the default gateway which is of course in the same network too.

    I need two fully operational ip addresses, but I realized that I can't have two interfaces (routed interfaces) in the same network segment. I have just a single router (Cisco 2911). A friend told me that I might be able to set this up using VRF, but as far as I have read, there is no way to use VRF to achieve this.

    Is it possible to use two (or more) ip addresses to redirect traffic to the same default gateway in the same router?

    Thank you!

    Miguel

    Hi Miguel,.

    If you want just your 2911 have set up two public IP addresses, you can set one of them as secondary IP address. Suppose that 192.0.2.1/29 is your default gateway, and 192.0.2.2/29 and 192.0.2.3/29 are your IP addresses. So to have both configured, you'd:

    interface Gigabit0/0/0 ip address 192.0.2.2 255.255.255.248 ip address 192.0.2.3 255.255.255.248 secondary
    And voila - that should do the trick :) Best regards, Peter

  • 2605dn will not print from a computer, but another computer on the same network print very well.

    The two machines running Win 7 64 bit, both on the same network (such as a printer) all with cable connection to the local network. A single machine prints fine, but since a few days, my PC will not be printed on the printer. PING and TRACERT it is correct, and I tried removing/reinstalling the printer several times. Using the PCL6 driver, as well as a specific driver for printer have same results.  Anyone else having this problem?

    After almost 12 hours of continuous hair-pulling, finally ran across the solution on a Microsoft forum site: it turns out that the problem was a recent update of anti-virus software (McAfee, specifically) who changed the firewall settings.  Can't seem to get the AV software allow constantly to the printer, but temporarily disable the firewall in the AV software has solved the problem.  (the other machine running another AV software package)  I have to just be careful during this 15 minute period.

    Anyway, if you have a similar problem, make sure to check the firewall settings.

  • Photosmart Prem C410 all-in-one: our laptop and printer AiO are on the same network, but laptops can 'see' printer

    Our two portable Windows 10 both our Photosmart Prem C410 AiO printer are connected to the same network (as evidenced by checking the name of the network of all 3 devices).  We were able to connect between laptops and printer without problem (printing, scanning, etc.).  A blow, or laptop computer can "see" the printer.  I uninstalled and reinstalled the printer on two laptops, but when I enter the IP address of the printer as part of the installation process, I get the error message (on computers) "your printer is not found on your wireless network.  I used the wireless Wizard connect to the printer, restarted the wireless router and restart the two laptops... the IP of the printer stays the same every time and laptops and printers continue to be connected to the same network named.  Help

  • Can I share an e-mail address between a pc and a laptop computer in the same network?

    I would like to be able to access Outlook from my laptop when messages are received on my pc main workstation, advice on how to achieve this? Thanks for any help.

    There are several ways to achieve this.  One way is to use a tool of office connectiopn RDC, VNC, GoToMyPC or Teamviewer.  With tools like these you really not use mail on both computers, but using a PC to access another PC where Outlook.

    Another is to install Outlook on the second PC and configure an account that will access the same mailbox as the access one the first PC.  You share contacts and calendar, but you can receive and send messages on computers or both, with the same e-mail address and it is not too difficult to get contacts and calendar from one PC to the other.

    A third is to place your Outlook data file in a folder that you share on your local network and access to this data from a PC file.  If it is not a recommended approach, it works, provided you don't try to access the data of these two pieces at the same time, and you'll have all your mail, contacts, calendar, tasks, etc. available on both computers.  You will need to make sure that you back up your data frequently as well, just in case, Outlook because Outlook is not designed to work in this configuration.

    You can also buy third-party tools that will enable this type of share, you want.  Here's the safest which provided the data from the file on the network, but they are not free.

    In the future, please ask Outlook questions in the forum for your version of Outlook Outlook.

  • Practically in segregation a virtual machine within the same network

    We have a VMware ESXi 5.0.0 (504890) host that has physically 4 network cards. We run 3 VMs on that host and turning a new config. However, this new virtual machine will replace our old Windows DC, DNS, server DHCP etc., and we'd like to config it before going live - will not perform us a migration of swing. We are a little worried that it can interfere with our direct network and that's why I would like to somehow almost segegrate it.

    For the moment, we have a single vSwitch0 linked to all our VMs and management card:

    vSwtich0.png

    What is the best way to do this so that our new DC (with the same domain name and within the same network) can be configured without it interfering with the current network.

    Thanks for your comments.

    Oliver

    Hello

    You can create a second vSwitch without physical network interface cards. Create a VM Portgroup on this vSwitch.

    You can configure your new virtual machine to use the Portgroup. So, he won't have any connection to your network.

    The good thing is, when you want to test things with a customer, you can create a second VM and configure it to the same VM portgroup on the second vSwitch.

    Two virtual machines on this Portgroup can communicate with them because the traffic is handled internally by the host.

  • SC network can be on the same network as the network of the vm?

    Because of our limitation of network design, we put the HC network on the same VLAN. There is a problem of security here, but beside that, there are other concerns with this design? Thank you for the feedback.

    Daniel

    I did this without any problem.  Better to be on a separate network, but works very well with all on the same network
