Ola, moitas grazas por contestar tan rápido e desculpa por non engadir toda a información necesaria para que me poidades axudar.
Teño router, as veces conéctome por dhpc e outra configuro eu a IP, nos dous casos sempre abro os portos a esas IP's, en Windows sempre me foi así (xa sei que isto non é windows).
Conecteime ao Amule e dame id baixa, pero ademais cando fago: http://www.internautas.org/w-scanonline.php dame que o porto esta fechado.
Buscando por Internte fixen o de UFW, pero nada, non pasa nada. Logo dixéronme que mirara o das iptables, e resulta que si están activadas (deben vir así de serie, uso ubuntu 10.04 64bits) entón instalei o Firestarter e aceptei esas conexións e nada. Reiniciei como 10 veces, volvín a facer todo como outras 10 veces.
Creo que me vou a suicidar. :(
Os portos que quero abrir son o 85 para TCP e 1985 para UDP
