  • Is it possible? - 2 subnets on one W2003 server

    Hello!

    I have a question regarding networking on Win2003...

    We have 2 different subnets in our company....

    Right now I`m buying a HP server, that will be able to host some VmWare machines..


    Main network card, which will be used for GREEN network (LAN) would have an IP: 192.168.1.13 for example...
    On this network&IP would also be 2003 host, which would have 4 VmWare machines on it..

    Now the problem...

    Is it possible to have 2003 host on 192.168.1.0 network na all of the vmware machines on it on 192.168.2.0 network.

    I can make 192.168.1.0 visible to 192.168.2.0...

    So Win2003, 2 network cards each card on different subnet...

    Can I do this?


    Thanks!

            I second the "WTF". I see Jason posted a cute dig on another post and reported he got dinged. So if you're trolling for negative rep, you'll have to take a shot at the OP or ???

              First let me thank you for buying HP. I have more stock to unload.

              I'm obviously missing the intent in your question. You can make one subnet see another through a router. So on the 1 HP server you have (for the sake of argument) two VMs, one on subnet 192.168.1.0 and one on 192.168.2.0 through NICs?

              Somehow you're going to have to route one subnet to the other or you could try going w/ class A (10....) or class B (172.16...) but 192.168... addresses should be private class C addresses (255.255.255... mask).

              I've seen people violate IP classing all the time, not that I'd recommend it.

              Real question is what are you trying to accomplish in a "business" (vs. "technical") sense that prompted your original post?
              Cheers,

                Thanks for reply!

                OK, the thing is, that I want to have 2 NICs on 2 different subnets on same server...

                Its sort of server for virtualisation, so I can have multiple vmwares on it, and I would like to see that for example virtual VPN server would be on 192.168.1.0 network and another virtual WEB server would be on 192.168.2.0 network.
                And both vmwares would be on the same machine...
                I have already made this 2 subnets on Smoothwall firewall...

                I know its complicated, but it would be interesting doing it, because I could remove 4 servers (boxes) with 4 vmwares (cheaper, safer, faster recovery)...

                Thanks!

                  Yes, it's possible and, unless it is difficult to assign hardware resources in vmware (never used it), it should be pretty easy to do.

                  Is there any specific question you have on configuring this?

                    Thank you!

                    So I configure one card to one network and second card to another network. Then in vmware I assign 2 virtual networks, each pointing to different NIC/network.

                    Are there any problems with multiple gateways?

                    This computer is part of a domain...


                    About resources...

                    Server has 6 GB RAM (will expand it to 10 GB) Xeon dual core @2.44 (I think thats correct speed ) and all it has to do is run 4 VmWare machines

                    Easy as pie

                      Yes, you should only have one gateway configured per machine (i.e. one for the host, one for vm1, one for vm2, etc.). Note that the VMs can have different gateways (relevant to the subnet they're on) than the host, but they all should only have one configured.

                        OK I can understand that, BUT how to configure SECOND NIC on main server
                        2003?

                        What options to use, which protocol to add/remove etc..

                        Thanks!

                          The "main server" is the host server right? Just remove the gateway from the TCP/IP properties on the host server. Each VM should have its own TCP/IP properties to configure.

                            That did the trick...

                            Our company just saved 5 extra servers that are now running on VmWare

                              I hope you got a percentage of what was saved. I am assuming OUR percentage cheque is in the mail.
