Looks like I have a slightly different situation than you're describing. I'm not specifying a "set ipcp ranges" anywhere. The peer chooses an inside address that's different from but within the same /24 as its outside address. I'm trying to run everything within two /16s over the VPN (which include those addresses). So I guess I'm getting the same routing loop but in a slightly more complicated way. Taking out my "set iface route" lines in mpd.conf made it no longer crash and I can talk to just the VPN host. So I tried next a "route add vpnhost mygw" before starting the VPN. It worked. So that's definitely the problem. It would be nice if there were a slicker way of doing this (mpd automatically adding that route if this situation occurs?), especially since I'm on DHCP. And it does make me nervous that mpd can make the kernel crash at all. But I can at least work around this now. Thanks a lot for your quick, helpful response.
