can't ping remote tunnel endpoint

Hello. I am using gentoo with a 2.6.10-r4 kernel. I have built the aiccu ebuild, and ran it (also i have NTP working) and it did print out the details of my tunnel correctly, but it did not create the sixxs interface.
About aiccu, i get in log:
Jan 14 22:53:05 [aiccu] Succesfully retrieved tunnel information for T5872_
Jan 14 22:53:05 [aiccu] Running as PID 29106
Then, i followed the instructions on http://www.sixxs.net/faq/connectivity/?faq=ossetup&os=linux (the *new* iproute2 method). When i type in the last line (ip -6 ro add default via via 2001:15c0:65ff:1f::1 dev sixxs) and i get: RTNETLINK answers: No route to host.
For fun, i try aiccu autotest and it goes fine till 6, this is the first one that doesn't succeed, and then all after it fail too.
###### [6/8] Ping the IPv6 Remote/POP Inner Tunnel Endpoint (2001:15c0:65ff:1f::1)
### This confirms the reachability of the other side of the tunnel
### If it doesn't reply then check your interface and routing tables
### Don't forget to check your firewall of course
### If the previous test was succesful then this could be both
### a firealling and a routing/interface problem
connect: Network is unreachable
I have iptables on, but i have proto 41 open. Also, ping6 2001:15c0:65ff:1f::1 worked at some point, but i can't remember what i did before it stopped working. It was the only address i could ping anyway, ping6 www.kame.net didn't work back then, and doesn't now either.
I would also like to know if there is any way to "clean out" the sixxs interface and it's routes to *try again* the whole thing.
Thanks

to 'clean', try shutting down aiccu and 'ip tun del sixxs'.
but first, i'd say you're missing an address on your tunnel interface, which would supposedly also set the route to your default gateway.
also, on gentoo, have you considered using /etc/conf.d/net and 'cp /etc/init.d/net.eth0 /etc/init.d/net.sixxs'?
when you setup the tunnel in the 'preup()'-function by
'ip tunnel add...' and
'ip link set mtu...',
you're ready to go.
to really help you on this, be sure to paste 'ip -6 addr sho' and 'ip -6 ro sho'.

eth1 - interface connected to ADSL modem, eth0 - interface connected to LAN, ppp0 - interface created for ADSL connection (network traffic goes trough this one, eth1 is more or less a dummy)

Nevermind, i got it working :-)
I still have two questions though..
Do i need to first configure sixxs using iproute and then start aiccu, or is aiccu supposed to do that (cause it doesn't here).
And, can u be more detailed about setting up sixxs trough /etc/conf.d/net and /etc/conf.d/net.sixxs?
Thanks

hm, yes, i could.
but just yesterday i noticed that gentoo scripts suck, so it won't work.
forget about it and do as you did before :)
