Hello, I just installed 2.3-Release on a P233 with a 3Com 56K PCI modem (one of the few non-winmodems - I think :-) -- it the one that only shows up on cuaa5). I configured PPP according to the guidelines on your website (the Pendantic PPP Primer). After playing with PPP, Natd, ipfw, and a few other things, I determined that my IP packets were getting sucked into a black hole, somewhere between the point where ifconfig detects the local IP address, and AT&T. Anyway, I have seen other people who have this problem on mailing lists, but I have not found the solution. I know AT&T uses CHAP for authentication, but I was under the impression that 2.3 was compatible with this, especially when you specify it (accept chap in ppp.conf). Upon connecting (I sent the PPP messages to ttyv7 (using syslog.conf), so I could watch it), AT&T and my system negotiate IP addresses, and then an ifconfig -tun0 shows the correct ip addresses, both for me and him. On the other hand, ping, lynx, netstat -r, ftp, nslookup, all hang, as if their packets were getting sucked into a black hole. They don't timeout or anything, they just hang, until I ctrl-c them. To make matters even more complicated, I tried it with my Mac OS X machine, and everything worked fine, including natd. Which speaking of natd, that's how I had to install Free-BSD on the P233, over my OS X box's natd link. I could not even get a PPP connection with the installer! I even tried re-downloading it and creating the disks on a different OS (Windows the first time, Mac OS X the second). I am pretty sure it's just something funky about AT&T, but I was wondering if anyone has found the fix.
