Trouble with dyndns

[Derfuhr]

Hi,

I have a game server running, I use dyndns because I don't have a static IP. After my IP has changed, no one can join this server anymore. It is possible to update the IP without restart server?

i use this argument when starting the server

/forceip=clumsysmurf.ddns.net

it seems the MP-Server resolve the IP at startup, but never again afterwards.
