    Hi guys, I have a set of virtual centos servers.

    I have 2 networks, 1 runs on the subnet 192.168.12.n and the other on 192.168.15.n.

    The 12 subnet has access to the internet but the 15 server doesn't

    I have a 1 centos server that is meant to sit on the two subnets, it has the ip addresses and

    The other servers all sit on the 15 subnet and have the ip addresses from 211 to 218.

    The server that sits on the two networks can see the internet but it can't ping the other servers on the 15 subnet and they can't ping it but they can ping each other.

    We have a set of windows severs that do work with this configuration so the network isn't the problem.

    Does anyone have any idea's?
