    icmp-id (read-only: integer) - contains the ICMP ID. Each ICMP packet gets an ID set to it when it is sent, and when the receiver gets the ICMP message, it sets the same ID within the new ICMP message so that the sender will recognize the reply and will be able to connect it with the appropriate ICMP request

    At this point (when PPTP client is successfully connected) if you try to ping any workstation form the laptop, the ping will time out because the Laptop is unable to get ARPs from workstations. The solution is to set up proxy-arp on the local interface.

    /interface ethernet set Office arp=proxy-arp

    :
    "NetBIOS Frames or NBF protocol is a non-routable network- and transport-level data protocol"
    :
    "Because NBF protocol is unroutable it can only be used to communicate with devices in the same broadcast domain, but being bridgeable it can also be used to communicate with network segments connected to each other via bridges."
    ppp / L2, PPtP, SStP/ BCP .... SStP TCP !
