This works on serial, here is the ppp log:

What is wrong with it. The serial connection works ok, so why not the usb connection?

My network:
INTERNET - ISDN - Smoothwall - D-link NAT Router - LAN - Windows computer

The linux on the smoothwall box:
Linux smoothie 2.4.32 #1 Mon Dec 19 11:36:53 GMT 2005 i686 i686 i386 GNU/Linux

This is a neat site, really helpful people.

Best regards,
