[pptp-server] "Ignored a SET LINK INFO packet" in FreeBSD 4.1

[John Heyer]

I had pptpd running in FreeBSD 3.2, but ever since upgrading to 4.1 it's
no longer working.  The clients authenticate and I can see the tunnel come
up, but it proxyarp never seems to kick in.  The main error I'm getting is

CTRL: Ignored a SET LINK INFO packet with real ACCMs!

I get a duplicate about 35 seconds later, then a GRE read error.  Does
anybody know what this means?  my /etc/ppp/ppp.conf appears below
