IPv6 testing
-
Well, I figured it was broken. But Apple OS X does not have a dhcp v6 client. So testing that is … awkward.
I'll add it to the list.
If you need to test updates on the DHCPv6 reserved leases, let me know and I'll be happy to do that for you on my installation here.
I still prefer to know what IPv6 addresses are assigned to my servers instead of having them assigned a random IPv6 and make them accessible via registering the lease in the DHCP. So I'll be using the Windows DHCPv6 service in the meantime. A difference between the Windows DHCPv6 service and the pfSense DHCPv6 service I noticed is that in Windows I need to register a static lease based on the DHCPv6 IAID and Client DUID and with pfSense it's based on the MAC address like with DHCPv4. What's the difference and why is there a difference?

Quick question, under System: Advanced: Networking: IPv6 Options, do we need to have 'Allow IPv6' checked? I noticed when its check, I see local-link IPv6 addresses are being blocked by my LAN rule(Allow LAN Subnet only). When its unchecked, I dont see them being blocked.
-
I just committed a filter rule fix for a typo.
That setting should be checked to have any hope of getting somthing ipv6 through pfsense. If it is unchecked all ipv6 traffic will be blocked without being logged

Is it correct that with the smos IPv6 getsync, static routes al only possible with ipv6 routes?
I'm trying to add a ipv4 static route and it is not working, it stays blank.Maybe for the buglist?
thnx.

OSX does have a dhcp v6 client, right? When I go into the advanced options in the interface settings, there's a spot for ipv6. Or, is it something else you were talking about?

Is it normal to see link-local addresses in the dhcp log? I don't think i noticed it before but I just had a major issue after a git sync an hour ago. The DHCPd service hang while it was trying to read the /var/dhcpd/var/db/dhcpd6.leases file. I deleted the file and that seem to fix the issue.
If i change my LAN firewall rule to LAN subnet only from any any, I don't see the dhcp messages anymore but now they end up in the firewall log.
Thinking of blocking fe80:: on the LAN so I dont see it in the firewall log but I dont want to break autoconfig of ipv6(not sure if it would or not)

without link local addresses you can not connect to the dhcp server. What is most likely here is that I am missing a rule that allows access to the dhcp server.
Thanks for testing. I'll go build a dhcp6 leases status page and a diag_ndp.php page for neighbour listings. It is now included in the snapshots and can be run from the command page with ndp -a.

Thank you for building this into pfsense!!! As you build it, we will test it :-)

Well this is great I did a fresh install onto my test system synced with the IPV6 git right away and setup my ISP's Native service only took bout 2 hours lol. I did have to change/add a line in interface.inc file as well need to find a place to have it auto run a route command when the connection comes up.

Catching back up since you fixed the issues with IPv6 patches working on BETA5…..
I have set the interfaces back up but i get the lovely oddball of the WANIPv6 address showing up in the config screen for the interface but not actually being applied to said interface. If i ping the address from the console on the pfSense box itself i get "ping6: UDP connect: no route to host" and as such cannot get any IPv6 traffic to egress thru the firewall. Internally I am getting DHCPv6 leases and can connect to the LANs IPv6 address just fine.

Not totally sure where it goes wrong here, but usually in my setup if the default route is gone, I go to System –> Routing --> Edit your IPv6 gateway --> Don't change anything --> Click Save --> Click apply changes and try again. This usually puts the default route back in. Can't really define yet where and why it gets lost.
I'm now using a /48 IPv6 block from Hurricane Electric so I can have pfSense 2.0b5 assign a different IPv6 /64 block to my wifi connected NIC and a different /64 block to my normal LAN. Both my wifi connected devices and my lan connected devices are able to communicate using IPv6 to the internet and towards each other now. Works like a shiny christal ball. Absolutely amazing stuff.
By the way, the captive portal stuff does not work yet in 2.0b5. I'm getting this error when enabling it:
php: /status_services.php: The command '/usr/local/sbin/lighttpd -f /var/etc/lighty-CaptivePortal.conf' returned exit code '255', the output was '2011-02-11 00:08:44: (configfile.c.912) source: /var/etc/lighty-CaptivePortal.conf line: 186 pos: 1 parser failed somehow near here: (EOL)'
Not sure if it's related to this gitsync and/or IPv6 and if I can and should report it somewhere. Does anybody know?
-
its not the route that's missing, I cant hit the IPv6 address of the interface at all even from the firewall.
EDIT: never mind. had wrong subnet in place. I can ping out as far as the gateway for that interface from inside, cant go farther than that though for some reason. still digging thru configs
EDIT2: that problem was related to resaving the default gateway on the interface. 5x5 on connectivity now on IPv6

I have not touched captive portal at all, so that likely won't work. I'll see if I can somehow duplicate the static route issue. I'll try and setup a new vm and see where that goes.
@Daboom: what needed changing in interface.inc? The routing issue is known. Oh crap, I just rememberd something about the route. I'll go investigate that likely cause.

I needed to add the line "set bundle enable ipv6cp" somewhere in the mpd5 config in order to allow it to accept ipv6cp config from my ISP. Now I have no idea where to stick it so I put it under something else that is commonly used. I wonder if you could get away with just putting that line in there anyways and it shouldn't bother anything else during the pppoe setup so it's always enabled kinda thing. If not you would have to make a special option for it in the pppoe section as a optional option. Also the route issue I am not sure if there is one specific for ipv6 in the config for mpd5.

I just added that line to the mpd5 config section so that is now in the tree, we'll know soon enough if it breaks anything else. Checking the default route issue next.

Another question for who might be able to answer it. My traffic logs are now flooded with local LAN IPv6 traffic. Check the attached screenshot. I wonder why. If I do a trace on any of these machines towards the other (which are both on the same physical network and within the same /64 block), it always reaches it directly and not via the pfSense gateway. How come this pfSense gateway does pick up the packet from the LAN anyway and list it as being blocked in the logs?
-
@Databeestje, another one for the todo list I'm assuming anyway. The interface statistics do not count the IPv6 traffic. The traffic graph does display the traffic though. Check the screenshot.
By the way, does it help you if I (we) report IPv6 issues with pfSense 2.0b5 to you via this forum or is your todo list big enough already and you don't want any more issues on the list? :)

Koen, I think that the blocks that you are seeing, are states that have expired.
The same can be seen in v4 after you have, for instance, logged into dropbox with your browser and then closed your browser window.
As far as I know, it's harmless and expected behaviour, but correct me if I'm wrong!
