PfSense and Hardware Firewall blocking Dropbox.com using pfBlockerNG.

I have upgraded my pfsense firewall to 2.3.2, since then I cant get to dropbox.com. I'm not savey with pfsense so I cant figure out  what is wrong.  I have added pfblockerNG so I figured that must be blocking it.  I out in a exception rule for the domain name www.dropbox.com and this does not fix the problem.  Please be patient with me because I am fairly new to this Hardware firewall stuff.  By the way I did disable Windows firewall and Virus protection on my PC and still no luck.  Any help will be very appreciated so thank you in advance.

Are you able to reach dropbox.com if you disable pfblockerNG ?

I just tested it, and yes I can get to dropbox.com if I disable pfblockerNG.

Which would indicate that your initial diagnosis was correct, and the problem is indeed with pfblockerNG.

What is your intended use for pfblockerNG ?

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

The best way I can explain it is: to filter out known BAD Addresses.  I would also like to stop the internet from scanning my ports and stop brute force password attacks, however I haven't been able to figure that out either.  

When, I disabled pfBlockerNG, (like you told me to) I was able to get to dropbox.com.  I re-enabled pfsenseNG, and reloaded filters,  I can still get to dropbox.com site.  Not sure whats going on but disable and enabled worked.  What do you make of that ?

pfblockedNG uses external lists of addresses to create deny rules based on address, by itself it will not stop port scans or brute force attacks.

from what you have described, it would appear that some part of your configuration of pfblockedNG is adding the address(es) used by dropbox.com to a deny list.

I would suggest that you removed and re-added pfblockerNG, and made one configuration change at a time, leaving it for the same time that it took to block previously, by this process you should then find the configuration change that is causing dropbox.com to get blocked.

OK, I understand what you want me to do, so I will begin now and try this.  However, I think you should know that I have looked at the deny logs. I can't  see where it dropbox is being blocked because I think the IP address change every hour or so. Do you think I'm correct in saying this ?

ArneLoviusCommented:
er, no you're not correct.

dropbox.com isn't a single active address that changes, it's multiple address with global load balancing.

Thanks to you, I figured it out.  It is the HiJacker IP database that is blocking it.  Since this is a table that is down loaded from iBlocker, Im not sure how to remove it from the table. 162.125.0.0/16.

Any thoughts?
