Thanks! Your patch worked so now there's no problem getting outside
using natd.
I've gone through the checklist in your original message as well, and
have found so far:
0) gif seems to work well (I use freenet6.net as my primary uplink
connection for IPv6)
1) /sbin/route somehow assumes prefixlen 64 instead of 0 for the
``default'' route. I've used this command to establish my default
route: route -n add -inet6 -net default -prefixlen 0 -interface gif0
2) Here's the output you requested:

3) IPv6 host autoconfiguration: tried w/o establishing the default
route, but couldn't have my box learn new routes. (Perhaps freenet6.net
doesn't support autoconfig; their setup script explicitly calls route(8)
to add the default route)
In near future, I'll enable IPv6 on another machine inside my box (which
is acting as a router) and try to run rtadvd/rtsol on these two boxes.
But currently still unsure whether it is allowed to run such a thing on
my machine; I'm not that familiar with the IPv6 addressing scheme (i.e.
I don't even know which address to assign to my internal machine), but
FreeNet6 might not like it if I run any routing daemon on my machine).
4) IPv6 communication via IPv6 router: for the same reason as in 3), I
didn't set my machine as IPv6 router (yet). I'll try this time and
circumstances permitting.
5) IPsec between 2 hosts/routers: still studying these topics. :-)
Things have changed since last time I tried IPsec tunneling using KAME,
so I can't set it up quickly (at least it seems that spdadd command of
setkey(8) has been extended a lot).
If there's anything else I can do, I'd be glad to.
Thanks,
Eugene
