dsl network enabled but internet not working

[Lenny86]

Hello to all,I am using knoppix 7.2 , I seem to have some problems with accessing the internet. I have a dsl connection (dynamic ip) type and I enable it but the internet does not work , for example I can`t use the 'sudo apt-get' commands because it obviesly gives connection error but i can ping myself, altough I cant ping any other sites also note that there is no error in the network connection it seems to be connected and ok here are some command outputs:

knoppix@Microknoppix:/etc$ ping localhost

Please tell us, which file do you have in '/etc/NetworkManager/system-connections' and what is the content of it? (You must be root to read it.)

[Lenny86]

[pppoe]
username='my username'
password='and the password'

[connection]
id=RDS
uuid=51867b63-ff06-4459-9a85-11fc3d816811
type=pppoe
autoconnect=false

[ppp]
lcp-echo-failure=5
lcp-echo-interval=30

[802-3-ethernet]
duplex=full

[ipv4]
method=auto

Everything coincides with what I`ve set up , the username and the password are ok too.
This exact connection worked before but suddenly something happend.
Could some ports be restricting packets???
