Hi Thanks for your replys. But it seems to be more ports involved. I try to update from ftp.gwdg.de with YOU on a suse 7.2 box. My bintec x1200 router logs the following lines on YOU connect. The IP 80.128.1.82 is the temporary IP of the router after DSL connect. The IP 192.168.222.11 is the IP of the SuSE 7.2 box Any ideas ?
