Hi, I have a problem with userland PPP that has persisted ever since 4.5 (currently using 4.6 and the problem is still there). I am on DSL and therefore connecting through the tun0 device and PPPoE. My problem is, that after some (varying) time, the connection just stalls. According to PPP's log, packets are still being sent out, but there is absolutely *no* traffic coming in. There is nothing in the log (even when set to "log all") that would hint at what is going wrong, it just suddenly stops receiving any packets at all. When I connect to the diagnostic socket, the prompt is "PPP". If i issue the "diconnect" command, it will change to "PPp" and hang there for a long time (up to a minute) and finally disconnect and show "ppp". If I type "connect", it will take another long time (up to a few minutes) until it finally connects and shows "PPP". While surfing the net, this usually does not happen. But if I start a big download (FreeBSD 5.0 ISO, for example) or run a program that quickly opens many sockets (file sharing apps), the connection will stall quickly (after a few megabytes of transfer) and once it has stalled, and I fix it by disconnecting and reconnecting, it will get worse and worse, stalling ever more often until I let it sit diconnected for a few hours. The FreeBSD box is running as a server for my home network (NAT and DNS). I have tested my DSL modem with a Windows box and it perfectly works, no matter what I do. So, it must be something in FreeBSD. Some socket / connection limit in the kernel or PPP I'm hitting, maybe? If anybody has an idea, I would be very gald to get some help with this, it has been bothering me for almost a year now.
