    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

    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

    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
