Well, Linux can handle it, but sometimes the PPP link goes dead with all
these fragment overlapping exploits. It's highly erratic, so I can't give
much details, but it works upstream and downstream, resulting in possible
DoS attacks. There is nothing in the log files and when you kill pppd and
restart it, the link works again. Has anybody else experienced this? I run
2.0.33.
