    John,

    I can guarantee to you that there are no dynamic routing protocol
    configured and no firewall in the network path.

    The server osr506b does not forward the packages between the interfaces
    when it originates from osr506c.

    This behavior can be seen by the command traceroute.

    The package is directed to interface 192.168.100.1 and dies.

    Thanks for your attention.

    Fernando
