I have a FreeBSD 7.2-STABLE box with mpd 5.3 configured as PPPoE client that connects to my ISP. If I make any PPTP VPN connection that goes through this PPPoE link my server hangs. I made some investigations and found that deadlock occurs only when pptp connection goes via pppoe link, connection from local network works fine. Deadlock occurs exactly when first data packet is sent through pptp connection. mpd can be configured as server that listens on my external pppoe interface or it can be configured as client that connects to other server in internet. In both cases it hangs. -- Bohdan Tymkiv Home
