...Right, i found out that i had to forward all my passive ports as well... i have no idea why, but now it works...

The basic principle is that any connections that are inbound (from the internet through the router to your home network) need to use forwarded ports. Outbound connections (from your home network through your router to the internet) shouldn't be forwarded (and don't need to be).

Passive port connections are made from the client to the NAS, so the ports have to be forwarded.

Active port connections are made from the NAS outbound to the client - they don't need to be forwarded in your router, but they won't work when you are double-firewalled (for instance, when using the client in your office).
