Kopete/Firewall
Si estás detrás de un cortafuegos o un NAT, tienes que abrir (y redirigir) algunos puertos para utilizar características avanzadas de Kopete.
MSN
To use MSN file transfers and MSN webcam, you have to open port (and redirect) 6891 to inbound TCP traffic.
Port 6891 is by default, but it is configurable.
We don't use (yet) a reflector. (A server in the middle of the transaction) That protocol is fully encrypted to keep out others to use it, but the amsn team may have already decrypted it.
