I've seen mpd crashes with Cisco VPN servers that are stupid enough to 
advertise their own IP address to the client, causing an infinite 
encapsulation loop (tunneled packets forwarded over the tunnel).

You could catch that with a sanity check inside mpd (don't accept the 
servers physical address for your own use during negotiation). I've not 
done this, we simply returned the Cisco box :-)
