Hi,

I just noticed that in OpenBSD 3.9 is't possible to have two lines in
/etc/mygate with the default gateway for both IPv4 and IPv6.
Until now, I usually added a line in /etc/rc.local with a 'route add'
command for IPv6.

For the machines on my network with a static IPv6 address configured on
the physical interface, the new approach seems to work fine.

But on my firewall/router, the default route goes over a gif tunnel, not
a physical interface.
When I add the other side of the tunnel to /etc/mygate, there's no
default IPv6 route after a fresh boot. When I add the line
route add -inet6 default <gw>
to /etc/rc.local or append the line to hostname.gif0, it works.
When in /etc/mygate, it doesn't. It's not a big problem, but I'm
curious what the problem might be. I don't see any error messages and I
can't pinpoint the problem when looking at /etc/netstart.

Any ideas?

From my /etc/hostname.gif0:

tunnel 208.201.244.209 208.201.234.221
inet6 alias 2001:05a8:0:1::0123 128
dest 2001:05a8:0:1::0122
! route add -inet6 default ::1
! route change -inet6 default -ifp gif0

I forget why ::1 is added as the default then changed to -ifp gif0, but
in any case it works great.

I have something similar in /etc/hostname.gif0 :

up giftunnel 82.94.107.210 194.109.5.241
up inet6 2001:888:10:9a8::2 2001:888:10:9a8::1 prefixlen 128
!route -qn add -host -inet6 default 2001:888:10:9a8::1

Works great too. But I was just wondering what goes wrong when I
remove the last line and put 2001:888:10:9a8::1 in /etc/mygate.
In that case I don't have a default IPv6 route after a fresh boot.
It works for my other machines, but not for this one with the tunnel.

Am I doing something wrong, is it a bug, or is the /etc/mygate sollution
just not intended to work with giftunnels?

It's not a problem, I'm just curious.
