ok, I found the problem... There must be something releted to how gurddog configure the firewall :|
If I turn it off, everything works just fine...
Has anybody managed to configure guarddog in order to let aMule work? I opened the required ports, but that doesn't seem to fully work because, as I said, I can't connect to any server but one or two... the puzzling thing is that when I'm connected, I get a high id... oh man!
