UDP and NAT errors

    I am running a solo computer with dualboot Mandrake 10.1 and Win98 SE.

    Azureus (BitTorrent) gtk-gnutella and EchoLink (communicating via the
    Internet) all talk about NAT errors, but still work. I am running an ADSL
    modem with NAT capability, but this is unused.

    EchoLink now refuses to work because of a UDP error, (it can list
    connections, but I can't get out) and this happens under Win98 and under
    Win4Lin. I wasn't running a firewall under Win98, so it wasn't the cause.
    Is this a Microsoft issue? I see that UDP is not an available protocol
    under Win98, and apparently cannot be added. It seems to be newer than
    TCP/IP.

    TIA,

    Doug.

    Hmm, that's odd, if your computer itself has a public IP address and
    not an internal one, I see no reason for this. If in doubt, update :)

    Well, the problem with EchoLink disappeared when I set up my modem/router to
    forward the UDP Port. Azureus is unchanged although I forwarded both TCP
    and UDP, and I haven't tried with Gnutella. Both work anyway.

    Two things I am not sure about in the Port Forwarding dialog: (a) the
    Private Port must be entered. I just entered the first number in the
    range.

    And (b) an IP address has to be entered. I just copied the existing one
    (port 161), which was No. 255 in the block that the router uses. Should I
    make them all unique, say, counting backward from 255? The block is
    192.168.
