DNSSEC on pfSense
-
Great! Installation works! I'm so excited!!! Thanx a lot!!
edit: second note) unbound works great! ping of hosts inside my LAN works. Name resolution is somewhat slower than before, but thats no problem…
Are you using forwarders or letting Unbound do all the name resolution? Also, is it slow just the 1st time or all the time?
-
Ok I gather nothing has changed in your config that you sent me originally, so let me check and I'll come back to you tomorrow.
Yeah, nothing changed in my config. How should I actually use these static dns mappings? Before it was done by dnsmasq and now with Unbound it says that I shouldn't activate the forwarder when using DNSSEC. So how should I configure this?
-
The forwarder is disabled. Unbound does all the job. As i can say - very subjective opinion - it was only the first call, say some minutes slow with every DNS-query, but then its mostly like before. I'm happy. Thats the best description of the actual state.
You did a really great work! Thanx again!
-
yup … give it try for now ...
resolve more faster than before@igor ...
can isee your syslog when firs time boot ?thanks

You can use the static dns mappings, its just the upstream DNS servers (forwarders) that it says you should ideally not use unless you are certain that they handle DNSSEC correctly. These static DNS mappings will be created as as local-zone in unbound and the relevant A and PTR record will be configured included a TXT record if you supplied a description.
So a simple dig zone @pfsense_ip will return the A record and a dig -x IP @pfsense_ip will return the PTR record. Likewise can be done for a TXT record.
Hope that answers your question.

If someone is interested in measuring DNS performance: http://code.google.com/p/namebench/
Just uncheck the other servers that are included by defalt, then do the test on your pfSense IP :)
It should give some numbers to compare the overall performance…

Who else here has multiple interfaces and has Unbound listening on them all?
Also anyone here with domain overrides (Services->DNS Forwarder) specified? If so are they working? -
Ok domain overrides are working. I still need to add an option for DNS Rebinding (enabling/disabling) as that was affecting domain overrides.
Currently it is enabled by default.Besides @jlepthien's problem of multiple interfaces been selected and for some unknown reason not been saved - any other requests/problems?
-
hi wagonza, on my side its running fine and stressless. Really a good thing of Software you created! Thanks a lot!!!
I don't have multiple gateways here to test that special funktions. -
Now it is working for me. I found the problem why he wasn't saving all my interfaces to the conf…
When I looked at the logfile I saw the following:
Dec 15 11:59:58 voldemort unbound: [9464:0] error: Could not open autotrust file for writing, /usr/local/etc/unbound/root-trust-anchor: Read-only file system
I am on embedded so I just mounted / rw and then clicked save. I guess you just have to implement the mounting rw on embedded with the Unbound package and everything should be fine then…

Oh, but wait. My OpenDNS is not working anymore… I have configured 208.67.222.222 and 208.67.220.220 as my global DNS servers but when Unbound is running, no urls get blocked anymore. Which DNS servers does Unbound contact for resolving?

Did you check "Enable forwarding mode" in the unbound configuration screen?
-
No. If you enable DNSSEC one should disable this I read…

No. If you enable DNSSEC one should disable this I read…
In that case I think it's one or another. Not really sure to be honest with you. Try enabling the option and test it using the test dnssec page and let us know if it works.
On the other side of the coin, I am not sure if OpenDNS supports DNSSEC? I thought they adopted DNSCurve.
-
Even with the option enabled, I still can access all forbidden websites. Also the DNSSEC test gives me Borat so that is working as well…
-
Unbound up and running here. When I get a chance, I'm going to set up a secondary on another server and have that pull from the pfsense…
-
Yes, this would work fine if you define the servers under services -> dns forwarder.
Hi, Scott. I am now trying to figure out how to do the zone transfer juju. I am a little confused, since I found an info page about Unbound that states specifically that it does NOT support zone transfers. I have seen this elsewhere too… Can someone shed light on this?

Go to the Unbound Status page and check the forwards option. It should display the current OpenDNS servers that you are using. From the cmd line you simply issue unbound-control forward - which will display the same info.

Correct - it is essentially a caching name server. There are ways to get it to return certain records for zones but it is not a BIND,DJBDNS,NSD or any of the others. Are you looking for an alternative to the DNS Package?
