Well,
I don't know for connections in Israel, as far as i'm in belgium, but I think that protocols might be the same !!!
So, to connect with OS X 10.1, for example using a PPPoe connection (like mine): you just have to check connect via PPPoe in the: preference panel, network, PPPoe and enter your log and pass.
Then, TCP/IP: select "connect via ppp" and enter your dns server.
That it's it.... Ireally like simple things wouahahaha.
Mac OS X 10.1 is build to support that transfer protocol without any soft.
Now, if you got another way of connection... just re-post and we'll see;
