      @Hugovsky:

      BUT, this is only try if I put includes in advanced config. With default config, I can start resolver with "Register DHCP leases in the DNS Resolver" set.

      Seems you're putting something invalid in there.

      server:
      include: /conf/local-blocking-data.conf

        I just set up a new 2.2 installation… unbound appears to be running, but these entries appear in the log whenever the service is started. I do have the options to register DHCP leases and static DHCP entries checked.

        Nov 25 19:15:29 unbound: [88622:0] error: cannot parse netblock: '/'
        Nov 25 19:15:29 unbound: [88622:0] error: cannot parse access control: / allow
        Nov 25 19:15:29 unbound: [88622:0] fatal error: Could not setup access control list

        Also, the service IS running, but the Status > Services page shows it as stopped.

        EDIT: Nope… it's not running. My computer is using the Google IPv6 DNS servers I put into pfSense, not the local resolver. I guess there's no way to have the router specify its own IPv6 address (even if it's link-local) for DNS to DHCP clients? I only know it's not running because my IP phone - which only supports IPv4 - can't resolve my VoIP provider hostname, and the only DNS server it has is the IPv4 LAN address of my box.

        This appears to be caused by the fact that I'm not requesting an IPv6 address on my WAN interface, just a prefix. Since there's no address, there's nothing to put in the access_lists.conf file, resulting in a access-control: / allow line.

        Bug 4046 created for this…

          Pretty sure you have to be running an old version, that was fixed over a week ago.

              I updated to the latest snapshot as of this morning (built on Thu Nov 27 00:15:05 CST 2014) and the above issue seems to be resolved. Now I run into something else. My computer (Win7) has both the IPv6 and v4 addresses of my box as DNS servers.  When I try to do nslookup, it appears that unbound is refusing queries to the IPv6 address, while queries via IPv4 go through no problem.

                That was tightened up a bit recently. It generally seems fine. The biggest functional change is it skips IPv6 subnets that reside on an Internet connection (a static interface with a gateway specified under Interfaces>[interface name], or any dynamic connection type). Is the subnet in question on an interface that's an Internet connection? Or is treated like one because a gateway is chosen under Interfaces?

                  No, it's actually my LAN interface, which has IPv6 as "Track Interface" (WAN, Prefix 0)… My WAN interface isn't obtaining an IPv6 address, just a /60 prefix.

                    Ok I see what was happening there, that was fixed today. Should be good on tomorrow's snapshot, or gitsync now.

                      Are entries posted in "Domain Overrides" being processed correctly?

                      I want to route any requests for hosts on the other end of my vpn to the pfSense that runs that network. This is something I had working perfectly using "Domain Overrides" within the old DNS Forwarder, but using DNS resolver it doesn't seem to be working.

                      My current config has the domain is set "vpn" and the server to forward these requests to is "10.30.1.1"

                      Are there any particular settings I should be looking at to get this to work?

                      Here is my log for an nslookup from my local network to server.vpn (Server is a valid dns entry on the other network and like I said, these queries were working with DNS Forwarder).

                      Looking at the log, I can see entires such as "server.vpn.local." - Why has the "local" been added to this query? (local, as your probably guessed is the DNS suffix for my local lan). My WAN DNS servers are Google (8.8.x.x) and Level 3 (209.244.x.x) and you can see that queries are being sent to these as well as 10.30.1.1 (the server which should be able to give us a result).

                        @mattbunce - have a read of this thread: https://forum.pfsense.org/index.php?topic=84184.0
                        Perhaps now the unbound requests are going out with source IP as the VPN tunnel local end-point, and the DNS server at 10.30.1.1 does not have a route back to that?
                        In DNS Forwarder (dnsmasq) you might have been using the "Source IP" field in the Domain Overrides settings to help this. But that field no longer exists for DNS Resolver (unbound).

                        Edit: add: Your client will be adding anything in its DNS suffix searchlist automatically, thus tryin server.vpn.local as well as server.vpn
                        Put the terminating "." at the end of the name to stop that;

                        nslookup server.vpn.

                        As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

                          So Unbound seems to have an issue where it restarts about every 70 minutes. Unfortunately I turned down the log verbosity because it was generating a massive amount of data even at level 1. So all I have are the start/stop entries. But here's a bit of the log…

                          Nov 28 00:41:25	unbound: [18673:0] info: service stopped (unbound 1.4.22).

                          I'll turn the verbosity back up and see if it provides any further enlightenment tomorrow… but given how much data it puts in that log file, it might be a bit harder to tell.

                            Hi, thanks for your help, reading that did lead me to something else… I'm not entirely sure what the "source IP" box was under DNS Forwarder, but I don't think I was using it. The only change I ever made was adding a couple of domains to the "DNS overrides" section.

                            I have realised a big error on my part though, I had set DNS Resolver to only use WAN, so without access to the VPN it could never send the request to the other server - Whoops!

                            So now I am getting a result, but it is slow, since the query is also being sent to my main WAN DNS servers, you can see this in the log below.

                            It seems strange that DNS resolver has identified this as a query that should be sent via the VPN, but it still sends it to the main DNS servers?

                              In the latest build,
                              2.2-BETA (i386)
                              built on Sat Nov 29 02:37:09 CST 2014
                              FreeBSD 10.1-RELEASE

                              There is a small coding logic error in /etc/inc.unbound.inc that can cause this PHP message:

                              Warning: in_array() expects parameter 2 to be array, null given in /etc/inc/unbound.inc on line 607

                              This code change fixes it: https://github.com/pfsense/pfsense/pull/1355

                              If you are on this build, and using DNS Resolver (unbound) then make this fix, or move up to a later build when that comes…

                                Good day !
                                After today's update the main page fixed now.
                                What about Unbound. I went into the very same issue https://forum.pfsense.org/index.php?topic=84146.msg461519#msg461519

                                The fix people provided did the trick :)

                                P.S. Borat is happy now.

                                Thank you !

                                BTW I had to put Routing-Gateways to proper values !!!

                                  Additional on the start/stop issue… A snippet of log from early this morning... this basically shows up every 60-70 minutes in the log. Doesn't appear to be anything indicating why the stop/start at log level 1.

                                  Is this to be expected for some reason? If so, what's the reason? Is it due to a setting I can turn off? I've been surfing when it happens and all of a sudden I get DNS errors because the service is restarting. It's a bit annoying.

                                  The S in IOT stands for Security

                                    Does the pid [3561:0] remain the same as previously?
                                    If so, then it is getting a message to reload its config, and I guess spitting out all that log stuff as it resets itdelf. That is still annoying if it has noticeable time when it is not responding to queries.

                                    What is in the system log around that time?

                                    Maybe there are real events happening - WAN down/up, a VPN down/up… that have caused it.

                                    As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

                                      Ok, so it's just reloading the config then… the PID remained the same until about 19:22 this evening, and it changed then because one of my interfaces bounced. Nothing else in the normal system log lined up with the Resolver log.

                                      Any thought on why the hourly config reload then? Could it be related to including DHCP hosts?

                                        DHCP renewals update Unbound's config and reload it, I'm sure that's all that is. dnsmasq is the same. It's not restarting the service and won't cause DNS to fail.

                                          Hi - Sorry to be cheeky, I was wondering if anyone had any idea what might be going wrong in my case when using Domain Overrides to send specific domain queries to a different DNS server. (You can see more in my post above…)

                                          @mattbunce:

                                          It seems strange that DNS resolver has identified this as a query that should be sent via the VPN, but it still sends it to the main DNS servers?

                                          Is anyone else using the Domain Overrides feature and do they also see the requests being sent to the wrong servers before eventually being sent to the correct one?

                                          Thanks, Matt

                                            Sorry to ask again but is there news about my issue reported back in page 6? Or is just misconfiguration I'm doing?
