Unbound request: ACL

  • Right now I'm providing DNS forwarder services to a network that is attached to one of my LANs. I am looking forward to trying Unbound and providing feedback, but for this I need to be able to allow said network to access it.

  • So just to clarify you are looking for a ACL configuration option to specify which networks are allowed to make use of the Unbound service?
    If so, I do want to add that - just havent had the time with holidays etc. I will see if I can get it done as soon as possible and will let you know once done.

  • My pfsense network looks like this:

    WAN: pppoe

    I have a single client device on the OPT1 network and it looks like this:

    LAN: (public subnet)

    This device in turn has a router attached to it that has:


    So pfsense is not doing NAT on OPT1, and it has a static route for with as gateway.

    My understanding from one of your other posts is that unbound will service and, but not If I am correct, then this is a deal-breaker for me, as I need to be able to respond to DNS queries for The built-in DNS forwarder (dnsmasq?) responds to all requests by default in pfsense, so it is working for me now. I would like to take unbound for a spin though. Thanks for your efforts.

  • Thats correct, Unbound currently only allows the networks that are physically configured on pfSense. DNSMasq doesnt provide this functionality (not that i know of) so it just listens and allows for any host to utilize the service. I will definitely add ACL functionality so a user can specify multiple 'non-local' networks. Hopefully will have it done by Friday, I will let you know.

    Thanks for the detailed info.

  • I have done the work for adding additional networks to a separate Unbound ACL's page. There are a few tests I just need to do to confirm all is working - otherwise I will commit tonight and update the package.

  • Let me know if you need a tester.

  • Ok I have committed the changes - reinstall and you should be good to go. Just remember to obviously add the necessary firewalls rules (which I think you already have).

    I must add a note indicating this in that ACLs page.

  • On first visiting Services: Unbound

    Parse error: syntax error, unexpected $end in /usr/local/pkg/unbound.inc on line 63

    Line 63 appears to be the last line in the referenced file, and this is what it looks like in my installation:


  • 2.0-BETA5 (amd64)
    built on Sat Jan 8 00:47:04 EST 2011

    Additionally, when I try to reinstall or uninstall the Unbound package, this is as far as I get:

    Removing package…
    Starting package deletion for unbound-1.4.7...done.
    Starting package deletion for expat-2.0.1_1...done.
    Starting package deletion for libevent-1.4.14b_1...done.
    Removing Unbound components...
    Tabs items... done.
    Menu items... done.
    Services... done.

  • Odd - i cant reproduce this. I have re-installed, uninstalled and installed and it works. I am on build 'Mon Jan 10 22:34:12 EST 2011'.

    Looks like an incomplete download of unbound.inc ?

  • That's what I thought. Can you post the complete file, or tell me how to manually remove the package so I can try a new install?

  • Success. Deleted two unbound directories and removed the package info from the config file. I was then able to install the package and start the service with my ACL active.

    Looks great so far, thank you very much.

  • Ok cool - glad you manage to help yourself out there. The incomplete download is a bit worrying will chat to the devs and see if we can possibly work around that.

    Let me know if you have any problems.

  • I bumped the version number due to an old bug thats been around since the incarnation of the unbound package  :-\

  • You can update the second bullet here: http://doc.pfsense.org/index.php/Unbound_package

    What's the bug fix? Is there a changelog somewhere?

    edit: I see it: http://forum.pfsense.org/index.php/topic,29771.msg165982.html#msg165982

    Looks like it doesn't affect me if I am using ACL though.

  • Unfortunately no change log online besides commit comments.
    There was a bug when reinstalling the package that an original configuration would be over-written with the default. However this wouldn't have happened to the new ACL section.

    Will update the doc site shortly.
