Sorry, kind of a dumb question. I'm trying to open a port to allow
DNS traffic (port 53, UDP and TCP). I tried a quick nmap from
outside my network, and though the tcp port shows up open, there's no
reading from the udp port. How can I tell if I've opened the port
correctly? Here's what I think is the relevant output from 'service
iptables status' - does this look right? Thanks much...
Did you do an UDP nmap scan?
nmap -sU -p53 <target_host>
Thank you for the assistance, all. I did this UDP scan as indicated and
it came back "open|filtered." Sounds right?
