It's normal. gre(4) has changed a bit after the 1.5 branched. It is now a
cloning device. To create a gre tunnel, you first have to create a gre
interface, with 'ifconfig gre0 create'.

Mmm that just reminds me... There's a bug in gre, fixed in -current but
not in 1.6. The fix was checked in back in August, but I guess the release
was too close for a pull-up.

So, to use PoPToP, you have to disable gre in your kernel, or use revision
1.20 of syssrc/sys/netinet/ip_gre.c.

Then, it should work fine.


That's how I did it, Anton. I never saved anything
for the swim back.
