    I'm assuming you are asking about virtual IP addresses on MSCS.

    Establishing another default gateway on your cluster nodes will not help a
    node in a different subnet ping your virtual IP address. Default gateways
    are assigned to a Windows network interface, not to specific IP addresses
    (virtual or node addresses).

    First, you should make sure that your virtual IP address is configured on
    the correct network (verify the resource properties). The IP address and
    subnet mask of the resource should match the IP address and subnet mask of
    other interfaces on that network. Otherwise, you will have a routing problem
    (hence no connectivity from other subnets).

    Second, if you have confirmed that your virtual IP address is configured
    correctly, make sure the network you chose is reachable from the machine you
    are trying to ping from. Can you ping non-virtual IP addresses on that
    network (e.g. node IP addresses)?

    Third, if your virtual IP address is configured correctly, and your node IP
    addresses can be pinged but your virtual IP address still cannot be pinged,
    then start troubleshooting your network infrastructure and hardware, e.g. KB
    article 244331
    (http://support.microsoft.com/default.aspx?scid=kb;[LN];244331).
