@isaacfl Is this normal? The first is what I thought the old one was, and then I see a 2nd.

@jknott said in Only SLAAC Gives Out IPv6 Default Route (win10):

Next, get the Android devs to join the real world. A lot of business users want DHCPv6 and some are going with Apple devices instead.

A while ago, I read the reason why Android doesn't support DHCPv6 and it frankly didn't make sense. Pretty much every argument they made against it could also be applied to SLAAC. I suspect someone has decided to not support it and isn't interested in facts.

Yeah, it makes no since, "Lorenzo" (a lead/top Android "guy") just dosnt like it thus it just won't happen, it been a LONG time fued/issue in the Android/IPv6 communities

@johnpoz yes you are right. I am a idiot for doing this and I am well medicated with my illogical paranoid self.

Thanks for all the replies guys. Good to know I've done something right for a change.

P.S. @virgiliomi your signature makes me chuckle :)

Hi!
When deactivating IPv6 in Windows there is not IPv6-address on the interface anymore.
Thanks for the hint with the RAs. I have to dig more into the topic. I watched my prefix the last few days and it did not change. Maybe I have to set up IPv6 statically on my servers with the dynamic prefix and configure the DNS server accordingly.
Some problems came up with node or better npm not finding the repository because it was not resolvable on a Debian machine.
I'll take some time to do this and post the result here.
Thanks for the help!

The way you have it is saved in the configuration and is "static."

@bimmerdriver said in ICMPv6 not working ipv6-test.com:

In the case of Telus, the unique part consists of 24 alphanumeric characters using 0...9 and a...z.

On Rogers, the IPv4 host name is based on the cable modem MAC address and WAN MAC and ends with .cpe.net.cable.rogers.com On IPv6, it's based on the cable modem MAC and the LAN MAC and ends with .cpe.net6.cable.rogers.com. I have absolutely no idea why the LAN MAC is used.

@wre136 I bet on https://redmine.pfsense.org/issues/8934 have own DNS on FreeBSD and get many problems with IPv6 DNS and Fragments. Disabling scrubbing helps. But then IPv4 DNS has same problems :-(

I have a similar situation here, running 2.4.4 on bare metal and my firewall log is giving me this:

Oct 8 17:29:27 fw2-hvk filterlog: 145,,,11000,ixl0.504,match,block,in,6,0x00,0x0f7c6,1,UDP,17,114,fe80::16cc:20ff:fe94:3f97,ff02::1:2,546,547,114 2.4.4-RELEASE (amd64) built on Thu Sep 20 09:03:12 EDT 2018 FreeBSD 11.2-RELEASE-p3

I'm running CARP while this machine is master.

I deactivated all rules that have IPv6 in it for that given interface. Requests still being blocked. I deactivated Block Bogon for that interface. Problem persists.
I have no floating rule whatsoever and I really don't know why that is being blocked. I need DHCPv6 for prefix delegation. SLAAC works fine. IIRC it used to work under 2.4.3.

After some time of testing I created an explicit rule that allows traffic type UDP to port 547 to the firewall. Eversince then DHCPv6 returned to normal again. I don't think this should be necessary, right?

You can find further logs in the attached file. The Forum wouldn't let me embed it. It got marked as SPAM then.0_1539096402880_pfsense_attachment.txt

Thanks

There was no existing ipv6 link local address.

However after I rebooted the device one was created, so yes it is not needed to manually assign one, the proper solution it seems was simply to add the ipv6 gateway and then reboot for it to be created.

As to why there was originally no link local device, I dont know, but this was the first bootup of the device, so I will be aware in future to do a second reboot to get one generated.

There is now a possible issue with dpinger tho, after bootup (and wan reset) ipv6 stays pending until dpinger is manually restarted and then it works, the issue that I can see is if I goto the status -> gateway screen, the monitoring ip is not populated, but is populated after the service is restarted. I expect this might be because there is no wan ipv6 configured, the configuration is now like this.

WAN ip4 static configuration.
LAN ipv4 static configuration.
LAN ipv6 static configuration using the ipv6 prefix assigned by hetzner.
Default gateways configured using gateways provided by hetzner for ipv4 and ipv6.

@johnpoz said in Working with Temporary IPv6 addresses.:

What VPN service support this?

I am self-hosting the VPN server.

@jknott said in Working with Temporary IPv6 addresses.:

@dhiru said in Working with Temporary IPv6 addresses.:

I want to route all of the IPv6 traffic on few of these machines through a VPN tunne

I assume the other end of the VPN has a different prefix. If so, it's just standard routing. All traffic for the far end of the VPN gets routed that way.

Yes. The VPN server is on a different ISP with a different prefix.

The DUID can change for a number of reasons, which is why we added the box to set it static. The DUID is probably what they key static assignments off of, so that's not too surprising to see.

So what you probably need to do is see what the DUID is now and then set it to that explicitly, then it won't change again.

@xero9 said in Upgrading 2.4.3-p1 to 2.4.4 breaks DHCP6c?:

Not sure if this is related, but after updating to 2.4.4 my IPv6 has stopped working. pfSense gets an IPv6 address on the WAN and LAN side, but no clients are getting an address on the LAN.

Probably not. In this case it's a Hyper-V issue and it never gets an address. If you haven't already, start a new thread with as much detail as possible.

I'm on latest Ubuntu. Can ping6 another host in LAN using it's FD... address but not the pfSense LAN. Weird...
Found! It seems I need to add separate a firewall rule to allow ULA subnet access the firewall.

@jimp Ok, agree to the technical details. I wanted to give a hint for how to solve OT's need for automatic registering.

I checked again how it works. The information comes definitive via DNS-KEY from the pfsense gateway IP. I see no need to store the name in dhcp too when the passtrough to BIND works this way.

I can confirm, that restoring DUID helped to change to former subnet. And now there is a entry stored in 2.4.4 config.

<global-v6duid>00:01:00:01:22:56:08:42:00:0a:9b:a2:91:a3</global-v6duid>

@jimp This seems to have fixed my Android device as well. Before upgrade to 2.4.4, I was unable to have v6 running on my network because it would cause my cellphone to constantly drop it's WiFi connection because it though that it didn't have an Internet connection. After the upgrade, it works perfectly.

That would be a dream! For now I wouldn't hold my breath. FIOS doesn't even support IPv6 and as far as I know since they've been selling off the business to Frontier I doubt there are even any plans to. Shame.

No. The point was that rule does nothing. It should be deleted.

I still maintain your issue is on the client.

I suppose it could possibly be a setting in the DHCPv6 server or something but I can't imagine what that would be.

Maybe something else on that VLAN issuing router advertisements? Just guessing.
