newbie trouble - Internet connection

[jobse]

Hello!
Having trouble with getting my internet connection to work under FreeBSD
5.2.1, although it works well under Fedora.
Am abel to connect to host(my ISP) and I am getting login/logout prompt
with statics about uptime etc. However I cannot get to
any Internet site. My ISP havent got a clue they say, they don't provide
support for OS:s other than windows -major drag btw.

thanks
