[PROBLEM] VPN established, but no files

[Sims]

Hi everybody, I've successfully connected to my NAS at home, and the connection is visible in my config. But when I try to find files from the NAS nothing comes up.

Terminal

Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
CHAP authentication succeeded
MPPE 128-bit stateless compression enabled
local IP address 192.168.0.2
remote IP address 192.168.0.1

Update:
When I close the connection:

Terminal

Sent 0 bytes, received 36609 bytes.

So no connection out, only in.
