    MLAT & ADS-B time reference errors

    Hi all,
    I think i am having some network issues with successfully connecting the MLAT server.

    I've tried rebooting the system, have placed the localhost IP address in a DMZ on my router, RAW data is set to 'NO' and I only have one version of Dump running as far as I can tell. Appears to be feeding to FR ok according to status page too.

    I've opened the ports 8754,8080,30003,30334,30002,31001-31004,19788 also, however as the localhost is in the DMZ this should not be necessary.

    I've highlighted the areas (i think) that are an issue.

    I can't see anything in the status reports above that suggest an issue.

    In http://locahost:8754/monitor.txt I also have the following;


    mlat-uplink-stats="0"
    mlat_problem="connection-broken"

    Does anyone have any ideas as to what the issue could be?

    You should not dmz or pinhole units you have a surveys reason in a high secure setup. It's a high security risk. All ports are requested via an outgoing connection first from app, So are authorised. Opening so many may just cause further issues
