A physical server with 2 NETWORK interface card using a virtual machine as IPS (transparent VM) and everything should work normally?

Hello guys.

Is there a diagram that I made, using for my self this question.

2067917_1.png

As you can see, I have a physical server with 2 NIC I don't want to use a VM (with Snort) as IPS / IDS system for inbound traffic on the management of VLANS. Is it possible to use this VM in this way (as an IPS/IDS, VM with two NIC without any routing work?)? Maybe you have a suggestion, how can I achieve this, as easy as possible? Maybe you have an opinion, what OS unix system do I use?

Thank you for your time and your answers. Any useful information is much appreciated.

Yes, it should work. You need to look out for, it's that the 'outgoing' NIC is not connected to the same physical switch as the entrant and that there is no link between these two physical switches, because this would create a loop of layer 2 on the network.

I haven't worked much with Linux, but I don't see that you would have a problem to find some Linux/Unix with the possibility to bridge two network cards and use some software IPS to inspect the traffic.

  • TCP on PC server with the network interface has 2

    If I need to create a TCP on PC server with the network interface has 2 with a different IP address, for example 192... and 172... and the IP address of the client side is 192..., is there something I need to take care.

    Any suggestion, thank you.

    No, by default the server listens on all interfaces.

    Network configuration / routing / two network interface cards / NAT - leased / dedicated Dell R210 running VMware ESXi 5.1.0 build-799733

    Hello

    I'm trying to understand how to configure a dedicated server of Dell R210 rented running VMware ESXi 5.1.0 build-799733

    This dedicated server is rented www.online.net and sits somewhere in France. One of its network adapters have an IP public 62.210.177.20x. The other NIC is here, but I do not understand how it is configured. According to the www.online.net portal, the other NETWORK card has or should have an IP 10.90.116.20x. And I am obviously set up is to have some virtual machines running and be able to access the Internet. I have access to the console of the server Dell through iDRAC and since I could see, one of the network adapters in the IP is 62.210.177.20x defined, and the other has been shown out of service. I managed to make it appear the other interface but I cannot find anywhere how to assign the IP address 10.90.116.20x to this 2nd network adapter. But then again I don't even know if I should or if I need to assing a IP address to this 2nd network adapter. What is the cable connected even for this 2nd NIC? I do not know. Should it be - I'm not either. I don't know French and manuals/instructions on www.online.net are in French. I can try an online translator, but I don't think that what I'm looking for is explained. How do I get this set up? I have to do something about the ESXi on the server console? This interface 2nd should be in place, or it must be down as if it was originally? Yesterday after watching someone videos on YouTube, I added the second virtual switch and moved the virtual hosts of this switch 2 and he entrusted the 2nd NIC. But that 2nd NIC had a red X next to it probably indicating that it was disconnected the 2nd form virtual switch. Today and now I have managed to access the ESXi console server through iDRAC, I bring the 2nd NIC, and now both network adapters are assigned to the virtual switch 1st . But I think that a NIC should be attributed to a single switch and the other card NETWORK on the 2nd switch. I'm just a desktop guy with enough knowledge to be dangerous J if you / someone put in steps how and where to set them up it... PLEASE

    Thanks in advance

    • VMware vSphere Hypervisor is an "operating system" for pure virtualization and support NAT or routing. Therefore, only a real bridge configuration can be used.
    • To use a subnet additional IP must be configured as a router VM.

    If I understand the above, I need to show some VM and set up as a router? If the virtual machine that will act as a router must have two network interfaces, where it is connected to a switch and the other to the other switch network card. Am I do? The YouTube video that suggested, but I thought that maybe / somehow ESXi can route packets between the two network cards, but from what I read, ESXi can route packets. Do I need to order an additional / extra / 2nd IPv4 address so that it can be assigned to the interface of the router?

    You are welcome.  Thank you for the additional information.

    Here is a card that should work for you:

    Read the reviews to see what users say about it.  You should disable the network adapter before you install it.  There is a PCI slot and the PCI Express x 1 slot is faster.

  • How many switches must be configured and min no network interface cards?

    Hello

    We will implement the ESXi5.0.

    We would like to know if we use different ports for network management and vMotion groups?  It seems that two of them use the same (different from ESX 4) IP address.

    In addition, my supervisor would like to know what is the minimum number of network interface cards to use (because the server has no slot PCIe)?

    Your opinion is requested.

    Thank you

    Since we implement VLANS on our site and based on the documentation, ESXi 5 gets only 1 battery IP, wonder what is the best way to cope.

    It is true that ESXi has that one battery IP, which is very good compared to the other two in ESX (Linux in the Service Console and the Vmkernel). However, we have only an IP stack means that it is the same driver tcp/ip, but does not mean that we cannot have multiple IP addresses.

    For example, you can create a Vmkernel how many interfaces you want and assign different IP addresses, which could be on the same network or on different.

    Even if you don't have a VLAN in your environment I would still recommend using another IP network for vMotion for your management. This will make the two a little more 'best practice', easier to different and you would be good too preperred if you implement VLANs in the future.

  • Private network between two or more virtual machines?

    I've been running an educational network configuration kind of base on esxi to work to teach their colleagues how running things. To do this I create a separate switch, connect the virtual machines to (only) the switch and run Ethereal on a machine with network in promiscous mode.

    Now, I would do it on my laptop. Can I do this with the merger? Can I network machines without connecting to the host (to ensure that there is no additional noise)? Can I configure a NIC in promiscous mode?

    sflanders wrote:

    I think the important part of the question is in regards to the networking VMs as they see, but not the host (btw merger networking of information: http://communities.vmware.com/docs/DOC-2527). Basically, it boils down to the host option only and the answer is no.

    In fact, the answer is yes because after that Virtual Machines are started can be simply down the vmnet1 network card and thus isolate the virtual machines between them.

    In other words on the network of Machines target virtual host-only and then start them up to the point where they receive their IP address DHCP host-only server, then in a Terminal on Mac (/ Applications/Utilities /) use the following command in low only Ethernet adapter of the host host.

    sudo ifconfig vmnet1 down
    

    Now the target of the Virtual Machines will be able to communicate only with each other and not the host.

    Note: You must down only Ethernet adapter of the host host after the virtual machines have acquired their IP addresses, because if you down the adapter before the Virtual Machines will not receive their IP addresses.

    The host only allows virtual machines to see the host, but it really shouldn't be any other "noise". Why do you have to be concerned about this?

    On the question of the noise, I think that VMware Fusion actually uses virtual hubs, no virtual switches (even if by mistake, VMware calls virtual switches), there is a risk of bleeding, and this has been discussed ad nauseam and various forums.

  • Best design for the use of 8 physical network interface cards on a 5.1 ESXi host

    I have 8 physical network cards to work with on and 5.1 ESXi host using Enterprise Plus license.  I need to repair the following traffic:

    Management traffic

    vMotion traffic

    Virtual machine traffic (probably 2 natachasery will suffice for this)

    NFS traffic

    Won't fault tolerance.  Natachasery-how much should I dedicate to NFS, vMotion, and traffic management?  What failover policy I should use (active / active) (active / standby) for each?

    It is business more licensing and vSphere distributed switches are used.

    Thank you

    Yes, I would put the backup in the switch as well as management traffic and vMotion is they use vSS or vDS. The other option would be to reduce your vDS for NFS traffic of 4 natachasery 2 natachasery and then or to add to the existing vDS that contains management and vMotion VM traffic to add it extra bandwidth or create a new vDS with these 2 natachasery. But at the point of my original thought around creating a vDS is based on all of my bandwidth throwing together and then cut it but I want it and do not have to trade around natachasery after the fact. But there are so many different ways to achieve that is the fun part.

  • MAC addresses of our network interface cards physical on the ESX host

    I asked a very interesting question.   What is the MAC address for each physical network cards within our ESX host.   Our host ESX3.5Update4 has 6 of them.

    I am able to ESXCfg allows to identify the vNIC but assimilates to the physical network adapters?   or, how can I find the MAC address of the physical network adapters?

    No, I mean there are additional MAC addresses that the switch can 'see '.  The service console interface have a MAC, and address that will be displayed if you run 'ifconfig', but vmkernel will not be displayed in this way, use "esxcfg-vmknic - l" to display this MAC address.  The virtual machine each have their own of the MAC you can get that from their configuration files, or the vi client.
