I have the same problem. RH7.0 with 2.4 kernel and everything works except downloading files. I keep getting the "Waiting 22s for 1 busy" error and eventually a "Couldn't download"

People are able to download from me but i can't download of others. My comp is connected to a linux box that is using IP masquerading to share a cable modem with several windows/linux boxes.
I guess i have to config a new rule for ipchains to allow Limewire 1.2 to work but don't know what. Can anyone help?
