Hi Arni, The one thing to note about CHAP is that the Authentication process is bi-directional. That is to say that, in a normal CHAP Setup your Router will send a USERNAME/PASSWORD combination to the Remote End and the Remote End will send a USERNAME/PASSWORD combination to your Router. This is not what you want, as you do not know what the other end will send back to you (apart from possibly the remote ends' hostname).
You should change the config on your side as follows: OLD LINE: ppp authentication chap NEW LINE: ppp authentication chap callin This should do the trick. I would be interested in hearing if this solves your problem or not. I would also question doing UNNUMBERED to ETHERNET 0 as the ISP will probably hand back an IP-Address to you, which could easily be assigned to the Dialer Interface, but that is another discussion. Have fun, Brian.
