If you have Link Quality Reporting (LQR) configured, it is possible that = too many LQR packets are lost between your machine and the peer. The = ppp(8) program deduces that the line must therefore be bad, and = disconnects. Prior to FreeBSD version 2.2.5, LQR was enabled by default. = It is now disabled by default. LQR can be enabled with the following = line: enable lqr [ie demonstrate how to enable it since it's off by default] Is Brian Somers still a FreeBSD committer? Section 14.9 has his email = address and suggests you contact him under some circumstances. I would delete 14.11 because openmode is now the default and 14.12 = mentions how and why you should disable it. Section 14.20 says that PPP doesn't dump core because it is run as root, = this is incorrect - it doesn't dump core because it is set UID. Section 14.22 could basically be replaced with "use 'nat same_ports = yes'", or suggest the user use PF for NAT and run the miniupnpd port. = Certainly these days games (and every other network app) are much more = NAT savvy due to its prevalence. I would also add a section about MTU - I expect the dominant use case = for PPP is ADSL these days. In this case the MTU is usually limited to = 1492 bytes (1500 byte ethernet frame minus PPP framing overhead). If all = ICMP is blocked at some part of the link then packet fragmentation = doesn't work properly and you end up with symptoms like interactive SSH = logins work but bulk SCP or FTPs don't.
