I'm running user ppp for my Internet connection. It basically runs fine but there is this quite annoying problem: Sometimes packets stop going out through the tun0 interface (pppctl shows queued packets) but there are still packets incoming (obviously the connection becomes unusable). The only remedy is to reconnect manually (I'm doing this via pppctl) or wait until this is done automatically when lqr is enabled. When does this happen? - many connections at the same time (e.g. running a file-sharing tool) - heavy CPU load A combination of the two factors usually result in the problem within some minutes. When burning Cd's there's a similar problem. First the bandwidth goes down really low but pinging is still possible - sometimes i also get disconnected. (But I could live with that problem since i don't burn CD's that often.) My configuration: I'm using FreeBSD CURRENT (but the same problem appeared using 4.8-RELEASE) ISDN-Card: AVM Fritz!Card PCI (passive) excerpt from kernel config #AVM Fritz!Card device ifpi #ISDN Protocol Stack (mandatory) device "i4bq921" device "i4bq931" device "i4b" #ISDN Devices device "i4btrc" 4 device "i4bctl" device "i4brbch" 4 #device "i4btel" 2 #device "i4bipr" 4 #options IPR_VJ #device "i4bisppp" 4 For ppp configuration I use isdnd.rc and ppp.conf.isdn from /usr/share/examples/ppp/ (only telephone numbers and login information changed) I couldn't find the cause of this problem so far. My best guess would be some kind of hardware incompatibility but there should be some remedy since it runs fine using windows. Any help would be appreciated.
