    Hi,
    is this possible?
    have a problem with a user connecting tcp over a network to a NATted IP
    address.. but saying his udp packets are being dropped.. problem is i
    can't see any UDP packets.. only TCP.

    Is it possible to test a udp port connection from the CLI say in
    unix/dos? ie. telnet 111.111.111.111 25 ?

    thanks in advance.

    You might be able to figure something out with unix traceroute
    which uses udp by default.

    http://www.die.net/doc/linux/man/man8/traceroute.8.html

    pathping may also be able to use UDP. Can definately use TCP.
    Not cli but Windows GUI.
