TCP/UDP Open Ports - ELIN Communication

Hello,

Does anyone know which TCP/UDP ports need to be opened on a router to make a LIN communication work ?

Thanks for your help.

  • I don't know of a list. But EuroPRP has port number 1264 (tcp and udp).

    The following information is provided to assist your IT department with firewall
    configuration:
    PRP uses UDP port 1264
    ELIN uses UDP. ELIN instruments always use port 49152. ELIN on PCs uses
    dynamically allocated ports.
    ELIN systems require both PRP & ELIN to pass through firewalls in order to function
    correctly.
    ELIN & PRP can cope with NAT, but they expect a consistent configuration. For
    example, if an IP address from another subnet is NATed to appear as if it is on a local
    subnet, ELIN & PRP will expect broadcasts to reach that IP address (this would require
    the NAT router to generate pseudo-broadcasts to ensure the packets reach the
    destination).
    ELIN expects all LIN nodes on a logical LIN network to be reachable from all other
    nodes. For example, if you have two LIN nodes inside a firewall, and two LIN nodes
    outside a firewall, all forming part of the same logical LIN network, then it is essential
    that both LIN nodes outside the firewall are allowed to communicate with both LIN
    nodes inside the firewall (& vice versa). Only allowing partial connectivity will cause
    significant problems, particularly for the LIN Network Explorer utility.
    Common practice is to allow hosts inside the firewall to initiate access to the outside; but
    not vice versa. If such a policy is adopted then it will be necessary to configure at least
    one of the ELIN nodes inside the firewall with the IP addresses of all ELIN nodes outside
    the firewall, in order to ensure the correct operation of remote cross-subnet learning of
    mapping (see section 3.1.2).

    Just discovered LINOPC needs to be added (allow connections) to the incoming rules on Windows Server 2008 R2. This is so ESDATASRV can connect and provide the LIN Data information as seen in the InTouch shellapp.
