Internet ip change to internal IP (Twonkymedia Server)

hi all,

if i connect my WD My book World over an external (dyn.org) ip i can open the twonky server Version 5.1). if i want to open a folder the connection string will be changed into my internal ip. somebody knows this problem?

i´ve changed the twonkymedia-server.ini into port 9000 but it doesn’t work…

HELP me please !!!
