If so, you may need the latest patch to ng_pptpgre(4) to work around a problem: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netgraph/ng_pptpgre.c.diff?r1=1.25&r2=1.26 Otherwise, I haven't heard of anyone else having that particular problem.. See if you have errors reported by 'ngctl msg ng0:inet.ppp.link0 getstats' (replace 'ng0' with the appropriate inteface name). > Also, is there any way to get DHCP to work with MPD rather than hard wire > IPs directly into MPD's config files?
