IMHO this is the correct way to handle this. I've tried that (the two I've tried were 10.0.0.1 and 0.0.0.1), but it doesn't seem be the problem, because it doesn't even make it that far. i4b sends a "Config-Request: PAP" and the ISP sends back a "Config-Ack: PAP", and then a few seconds later i4b sends the same PAP Request again. When the "PAP loop" by chance doesn't happen, then everything works fine. I believe my config is good, because I have a lot of experience with i4b, and this PAP loop only happens 40% of the time, and only with newer versions of i4b.

Anyone else working on if_spppsubr.c?
