A couple of days ago (without warning) my DNS server stopped resolving requests external to my local network. If I portscan my server from outside my local network, I see that TCP port 53 is open. I can use dig to resolve any host on that server as long as it is local, but if I try to to use dig from a remote host. It just times out. I thought I might have been hacked or something, but it does not appear that the named.conf file has been changed since 2015 (according to the stamp). Any suggestions as to what could be the issue?
