To correct my own error, gre is ip protocol 47. Ip protocol 6 is tcp.
Your statement about the kernel and pptp both trying to intercept gre
packets is pretty much correct.
Thank you for the suggestions. This problem is unique to NetBSD,
and I have been looking at ways for either pptp to use the gre
device or for kernel changes to allow pptp/pppd to get gre packets
even when there is a gre device compiled in but not turned on.
Since there is now a NetBSD pkg for pptp which I maintain, I will add
a note in the pkg documentation and at least a check at install time
for the gre device.
Thanks,
Darrin
