Unblocking Private IPs from Public DNS under PFSense
September 3, 2015
My home network has a domain name, so I don’t have to remember all the IP addresses of my various servers. However, I publish all the DNS information using AWS Route 53 since $0.50/month is much more palatable to me than running BIND. This works flawlessly until you get a firewall like PFsense that blocks all DNS responses for private IP address blocks (e.g. 192.168.x, 10.x, 172.16.x). Fortunately, it’s very easy to fix this under PFsense.
