On secondary:

    # tcpdump -i eth0 'port 24007'
    tcpdump: verbose output suppressed, use -v or -vv for full protocol
    decode
    listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
    ^C
    0 packets captured
    0 packets received by filter

On secondary:

    # telnet 10.XXX.58.95 24007
    Trying 10.XXX.58.95...
    Connected to 10.XXX.58.95.
    Escape character is '^]'.


Of course it can connect to itself.
