Description

Hi

I just setup some IPv6 site-to-site ipsec vpns.

Good news: They work

Not so good news: In the IPSEC status overview the tunnel shows down, but the SAD tab shows data going through the ipsec flows and tcpdump on enc0 verifies the traffic actually is going to the target via ipsec.

Probably just some sort of parsing issue...

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.

I just created a pure IPv6 tunnel between two VMs running today's snapshot and it comes up and works and the status shows the tunnel as connected. SAD and SPD tabs are populated as expected.

I'm guessing you have a configuration error that is resulting in the traffic routing outside the tunnel and not through it, such as having "IPv4" selected on Phase 1 and/or "Tunnel IPv4" selected on Phase 2. Either of those cases would result in the tabs not showing the proper output.

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 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.
