Added Domain to DNSBL Whitelist, still refuses to resolve

RonpfS

I don't have feeds.megaphone.fm in any DNSBL blocklist.
You can see which tables contain the domain with :

grep "feeds.megaphone.fm" /var/db/pfblockerng/dnsbl/*.txt /var/db/pfblockerng/dnsblorig/*.orig /var/db/pfblockerng/dnsblalias/* /usr/local/pkg/pfblockerng/dnsbl_tld /var/unbound/pfb_dnsbl.conf

and disable the feed.

Strange how the original domain resolves to another domain, your rss feed goes to another domain entirely. Nonetheless, I put podtrac.com and .podtrac.com in the DNSBL whitelist, rebooted the firewall, and it still fails. This is bizarre, I don't suppose you have more ideas of things to check.

Not really, I'm just a user. Try what Ron said.
Can you hit this URL from a PC?

https://www.podtrac.com/pts/redirect.mp3/traffic.megaphone.fm/IS9592789167.mp3

You already have the 2 domains WL'd, so...

Yup, I just clicked on that podtrac.com link to the .mp3 and it works fine from my laptop, but from my phone which in on the same subnet using the same DNS IP it fails with ERR_NAME_NOT_RESOLVED. It's bizarro world! Also, tried pasting that grep command and it fails. Why would it work on my laptop but not on my phone, hmm...

@fvultee Try adding .amazonaws.com so you have that, megaphone, podtrac, and hwcdn. That's what I see from my PC when logged. I'm out after that, sorry.

Maybe that is because the app uses HSTS :

You have to run the grep from the Shell or Diagnostics / Command Prompt.

I did indeed, she wasn't happy with it:

RonpfS

Well it means that this domain name isn't in any blocklist.
Test it with another domain from the Alerts Tab.

@fvultee @RonpfS What version of pfsense ? pfblockerNG? How much memory? What are the others packages in use ?

fvultee

I just disabled pfBlockerNG completely, it still won't resolve the domain. I hard set the DNS IP on two devices to pfSense, the same as my laptop which does resolve, but nope, they still won't resolve. So dang strange.

If your resolving and having problems - you need to figure out where your having problem following down from roots..

Do a dig +trace to find out where your problem is.. That returns a cname, which then would have to be resolved as well

$ dig feeds.megaphone.fm
