iChat - Videoconferenza FALLISCE

[Mat@Mac]

Ciao ragazzi scusate se magari sembra l'ennesimo post sui malfunzionamenti di iChat, ma per quanto mi sia sforzato di leggere i precedenti post non ho trovato un modo risolutivo x il mio problema.
Ho un iMac PPC g5 con Leopard 10.5.1 + ADSL e vorrei videochattare cn un mio amico che ha 1 iMac Intel anche lui Leopard 10.5.1 + ADSL, ma sia Videoconferenza che Condivisione scrivania non funzionano. Mi danno errore e nei dettagli del log appare ciò:

ECCETERA (troppo lungo)

Se sapete come darmi una mano mi fate un gran piacere.
P.s. Ho un router Telit AR520 e lui un Dlink T310

provate con altri contatti e poi mappate nei router e aprite nei firewall le porte usate dai vari servizi di videoconferenza e condivisione.
