I hope you might find some time to ponder this! well, from what i can see iPaq is trying to use Windows RAS service, where FreeBSD is configured to use PPP. is iPaq runs on WinCE? you should tell your iPaq to use Unix/PPP *not* Windows/RAS (Remote Access Service). please try this and let me know if it works. thank you very much for your time, help with testing and very good dumps. max __________________________________ Do you Yahoo!?
