No IPV6 after reboot!!!
-
I've rebooted my pfSense 2.2 box four times over the past two days - twice for snapshot updates. All times my Comcast IPv6 connection has come back online with no issues. I had issues in earlier builds where I would have to do a release/renew on my WAN interface to restore IPv6 connectivity, but that doesn't appear to be an issue for me anymore.
-
The recent problems occurred only when using unbound with specific interfaces selected.

You guys don't have a Comcast cablemodem link?
We're all fortunate enough to live somewhere where Comcast isn't the cable provider.

Hahaha… I have another option (FiOS oddly enough) but their equipment in my MDU building is old enough that they can only provide me with 20-25Mbps down service via VDSL, while I can get 100Mbps down service from Comcast for about the same cost for internet only. That combined with IPv6 (which Verizon hasn't even started rolling out anywhere) is why I have picked Comcast over Verizon.
But I'm definitely not a developer here... just a user. :)

Yeah, I read about the continuous drumbeat of Comcast grievances.
However, they've provided me with a rock-solid 55mbps link and early native IPV6 support. No V6 tunnels here… no complaints from me.

Ok…
So I went into the unbound settings... changed interfaces to localhost, lan, lan ipv6 link-local... changed outgoing interfaces to wan and wan ipv6 link-local. Saved changes, applied settings... unbound doesn't restart, in the log is...
Dec 4 21:31:40 unbound: [89497:0] error: cannot parse netblock: '/' Dec 4 21:31:40 unbound: [89497:0] error: cannot parse access control: / allow Dec 4 21:31:40 unbound: [89497:0] fatal error: Could not setup access control listThis is the same issue that happened last time I reported it in the DNS Resolver thread. I don't obtain an IPv6 address on my WAN, just a prefix. But I need to keep WAN in the outgoing interfaces for IPv4.
But this isn't about unbound, this is about IPv6 not working after reboot. So I reboot the box…
On reboot, unbound doesn't restart. But IPv6 itself works fine. Below is a ping to the IP address of a VPS I have:
Pinging 2604:a880:800:xxx::xxxx with 32 bytes of data: Reply from 2604:a880:800:xxx::xxxx: time=21ms Reply from 2604:a880:800:xxx::xxxx: time=22ms Reply from 2604:a880:800:xxx::xxxx: time=30ms Reply from 2604:a880:800:xxx::xxxx: time=21msOf course I can't use a hostname since unbound isn't started, but pinging the IP address works just fine. After I change Unbound's interfaces and outgoing interfaces back to all, it starts up and works just fine. I'm sure it would work fine if I just set Outoing Interfaces back to all… but not a big deal to me.
edit: regarding the unbound bug I mentioned earlier... the issue reported before was that this same situation happened with "All" selected when not obtaining a WAN DHCPv6 address, just a prefix... so the same fix needs to be applied to WAN as well.

That should be fixed by: https://github.com/pfsense/pfsense/pull/1365
which won't show up in snapshots until after 2.2-RC goes out to the mirrors, likely Friday.

Sure enough, selecting just WAN for outgoing interface and LAN + Localhost for interfaces works just fine.
