    Hello,

    I have had cflowd & cflowdmux (v. 2.1b1) working for a number of months now
    with no problems. However, about a month ago, we made some network changes
    (implemented a new router as the gateway) that would seemingly be
    transparent to this process. Ever since then, cflowd has not been working
    properly. Whenever the process is started, everything appears fine, syslog
    reports cflowd started properly, no errors, however, whenever I issue
    'netstat -an', cflowd (port 2055) does not appear at all. Thus, it appears
    as if cflowd is not attempting to bind the port as expected.

    Here are the appropriate logs:
