DNS Resolver

It doesn't seem to be picking up the aliases set for a host - creates the original ok, but not the aliases… I tried creating 1-5 for a few of my hosts, none of them work.

Settings do not stick under "advanced".
Attempted even checking random radio boxes and saving, same effect.

This should be fixed.

Hi

Settings does not stick only on advanced, in general settings happens to.

This should be fixed.

@mais_um:

I can't create a domain like mycustomdomain.com (10.0.0.50) and www.mycustomdomain.com (10.0.0.50) in Host Overrides, only one works. DNS Forward works OK

Ok will look into this.

@mais_um:

Can't delete networks when edit one access list.

Please check latest snapshot.

@mais_um:

I have a warning on Boot /etc/inc/unbund.inc file don't existe but /etc/inc/unbund.inc exist, i don't know if is a Caps problem Edited: The warning is not for file Unbund.inc is for unbund.inc no Caps

I dont see this error but check if it happens for you in latest snap.

Updating to 5 July from a a week ago seems having problems find some hosts, don't know why. I have to change to DNS Forward to solve this problems. One example i put the pfsense host name on Overrides and fail to resolve, some other works. The only change i make is using Vlans

Hrmm.. once you make the change and it stops resolving then could please PM me your unbound config file so I can see if anything is missing?

wagonza

@feld:

Settings aren't sticking

Can't resolve anything unless I disable forwarders

Disabling forwarders breaks my ability to forward domains to certain servers

Still the case in latest snap?

@stompro:

Can someone point me to the reasoning/discussion on why dnsmasq is being replaced? I've always been happy with it.

Well Unbound is now in base of FreeBSD 10.X so it makes it (pfSense) easier to maintain.

built on Tue Jul 22 01:18:23 CDT 2014 (Full)

Settings are sticking, i don't test if are working or not.
Can delete networks when edit one access list (what access list is for? been there or not is the same thing, some check box to only allow allowed lists? or i need one to reject all networks first?).
Hosts seems OK.
Host Override works but aliases don't.
Only the first domain works on Host Override. If i configure multiple domains to a IP or multiple IPs only the first one seems to work.
Not tested yet domain override. I'll.

Edit: My DNS clients take the DNS from General Setup -> DNS Servers (the first-one) and not the pfsense IP. My DNS Servers in system information and in interface are 127.0.0.1 and those in General Setup -> DNS Servers (should have my ISP to from my pppoe connection).

Edit2: For some reason My Ubuntu server 14.04 in VirtualBox doesn't resolve any host or domain said:

"xxxxx@BoxHost:/etc$ nslookup
> pfsense
;; reply from unexpected source: 10.0.30.1#53, expected 10.0.0.1#53"

10.0.0.1 is Lan IP (vlan) and 10.0.30.1 is another Vlan where My ubuntu server network are.

and dnsmasq has some really poor failure modes.

and … dense support is completely missing for dnsmasq

I can second the above in bold. I cannot get pfSense to serve itself as DNS, instead it pushes ISP DNS.
Am I missing something?

I'll third this… pfSense is not providing the router's IP address as the DNS server for clients to use when DNS Resolver is enabled. All works correctly when DNS Forwarder is used instead.

grandrivers

yes i noticed this also in 2.1.4 when doing some troubleshooting

Just to bump this: pfSense is not providing the router's IP address as the DNS server for clients to use when DNS Resolver is enabled. All works correctly when DNS Forwarder is used instead.

I tried with and without Enable Forwarding Mode. I also made sure that the override box in General Settings is off.

Also, slightly related, the dropdown options on the advanced settings page are all at the first option as default, while the legends/help texts underneath claim that default values are something else.

MikeV7896

Another bump, but also something different…

I recently changed back from ISP DHCPv6+PD to my HE tunnel, and in doing so I re-enabled the DHCPv6 server in pfSense. Anyway... after those changes were made, I disabled DNS Forwarder and enabled DNS Resolver. Pulled my network connection, reconnected it, and now my computer received my router's IPv6 address for DNS, but IPv4 DNS servers point to the DNS servers I've specified in the router.

For reference, my DHCPv6/RA setting is Managed.

Disabled DNS Forwarder and enabled DNS Resolver. The service failed to start up with the following error:

I haven't had a chance to troubleshoot further, but I'm happy to provide any other info.

I pushed an upgrade code to migrate unbound package configuration to 2.2 when it's installed, and also make sure unbound user is created during upgrade. It'll be available on next snapshots.

I continue with some problems:

I have to put on "DHCP Server -> DNS servers" my localhost IP, otherwise clients don't pick local DNS server and if i don't have DNS servers in "System ->General", does not get any . "Do not use the DNS Forwarder as a DNS server for the firewall" are uncheck. DNS Forward work ok,
One more time, Aliases in Host override don't work,
Can't redirect multiple custom domains to a local IP. Ex. mydomain.com and www.mydomain.com, only the top work the other get a non-authorirative sever to get IP if have any.

Behavior of Enabling Forwarding Mode

Services: DNS Resolver

Select: Enable Forwarding Mode

This adds the following to /etc/unbound/unbound.conf

# Forwarding
forward-zone:
    name: "."
        forward-addr: 8.8.8.8

The forwarding DNS server is read from what is configured in "System: General Setup - DNS servers"

This works fine. However, that is not the sever I want to forward to.

What I want to accomplish

I want to use unbound to forward to a DNSCrypt Proxy listening on 127.0.0.1 port 40.

I am doing this today with DNS Forwarder (dnsmasq) as documented in:
https://forum.pfsense.org/index.php?topic=78446.msg453441#msg453441

Attempted configuration

Since using the "Enable Forwarding Mode" checkbox picks the DNS servers in General Setup, I need a way to override that and use 127.0.0.1@40.

So, I deselected "Enable Forwarding Mode" and in the Advanced box entered:

forward-zone:
    name: "."
        forward-addr: 127.0.0.1@40

That Advanced configuration shows in /conf/config.xml. BUT, unbound never uses it and is not in forwarding mode.

Since that is a valid unbound configuration , why is it being ignored when you enter it in the Advanced box? Shouldn't these options be passed to unbound when it starts?

Hi

Someone please :), correct host overrides? thanks.

router_wang

The resolver is forwarding requests to my providers DNS instead of querying the root domain name servers. You can test this by going to https://www.dnsleaktest.com/

How can I configure it not to do this?

Go to System/General Setup- DNS Servers…

Uncheck- " Allow DNS server list to be overridden by DHCP/PPP on WAV"

Check- "Do not use the DNS Forwarder as a DNS server for the firewall"
