I have a pfSense firewall and a Windows 2008 R2 DNS server. I'd really like my DNS server to respond to external queries for my subdomains. Right now, I'm using a 3rd party service for that.
Is there a way that I can have my 2008 server respond to DNS requests from "the world" while still keeping it behind the firewall?
I've only got one external IP, currently. If needed though, I could purchase a second if that'd help in this situation.
