    This is a buffalo router, anyone know what the below means? Is it an attack or what?

    SRC is the source
    DST is the destination (you)
    PROTO is the protocol
    SPT is the source port
    DPT is the detination port (you)

    Port 139 is used in windows networking , port 4000 is probably a worm/trojian or someone scanning for one. Probably not someone scanning you in particular, you'll see a lot more of that type of thing

    I wouldn't worry about this at all. In fact, it could be that you initiated these connections (can't be sure without looking at the logs more). Port 139 is a Netbios request, which your router should drop and TCP 4000 is commonly used with streaming audio and video services. Uptodate AV software and OS patches on your clients and you'll be grand ;)
