    The client must see the broadcast, in order to connect to the server.

    1. What type of socket you have created?

    2. Is the client using INADDR_ANY or its interface ip to receive broadcast packets?

    The Client side and the server side are WINDOWS.

    broadcasts are only transmitted to the broadcast domain- in this case the local subnet. it is possible to configure some routers to forward broadcast packets. not sure if this functionality is avalible on a layer3 switch that has implemeted VLAN's.

    basically check the router and the switch for this functionality.
