ADSL with PPPoE

I use SuSE 9.0 and try to setup an ADSL connection with a fix IP address over PPPoE. Interestingly it worked, but I did something and it stopped working! My data: PPPoE: login name, password adsl-start shows me connected! and gives me an pppoe IP of 61.x.x.a and an opposite IP address of 61.y.y.b I cannot ping the opposite I address (maybe blocked by the provider) I setup my fix ip address in the network card info of YAST eth0: 222.c.c.37 the default gateway gives me already doubts: I tried 222.c.c.254 and I tried 61.x.x.b I cannot ping anything outside! I see the ADSL modem is flashing (LAN and WAN) though. netstat -rn looks ok for me as well as ifconfig. Any ideas? bye Ronald
