When your tunnels are up, can you attach the output of:

setkey -D

and

setkey -DP

That should help us with making changes to the parsing code, to ensure the output you see is the same as the output we see.

Thanks for getting back to me...

You are right, it was a configuration issue but a mean one :-)

If you select the local network in phase 2 using the dropdown it adds the network to the configuration as follows:
OPT1: 2001:db8:10::/64 -> racoon.conf 2001:db8:10:0:0:0:0:0/64

So when I have the compact version manually type on the other side it shows as down and actually traffic gets not routed through the tunnel...

Seems a bug to me, but not this one :-)

I pushed some fixes for exactly the issue you mentioned Andre.

I also committed a couple fixes yesterday that made it work for more situations. It was working if you entered the subnets manually but it was broken if you used a macro like "lan subnet". They should all work now.
