However, if MPPE is = negotiated, the client receives only about 1/4th(30-40 kbytes/s) of the = bandwidth available while downloading.=20 Download seem 'leapy' : it starts with high speed , then for a second or = two it stops completely then it bursts again. I'm not quite sure why = this happens, but everything goes back to normal when mppe is turned = off. I assume that this is due to the re-initialised key on every 256th = packet. Anybody seen that?=20 I tried different key lengths for the mppe but nothing changed. I = haven't tried the stateless encryption though, beacuse the clients = reject it. Here are the details : FreeBSD 4.9-STABLE pppoe: allow users enable mschapv2 enable mppe set mppe 40 stateful disable deflate pred1 utmp vjcomp ipv6cp ccp deny deflate pred1 utmp vjcomp ipv6cp ccp allow mode direct set mru 1492 set mtu 1492 set speed sync set ifaddr 10.0.0.1 10.0.0.15-10.0.0.20 set log connect command chap lcp error alert warning Regards, Emil Filipov
