Try nmap <your external IP> -- probably will be the same, bit… Also, nmap shows you open *TCP* ports, not UDP. Better than this would be to run netstat (like netstat -aln | grep 53 ) and see if it is listening on UDP 53.

Actually that doesn't really show anything about your firewall -- telnet does't understand the <IP>:<port> syntax, so it tried to resolve the name "184.22.226.205:53", it doesn't try connect to port 53 on 184.22.226.205. If you want to try telnet to port 53 on 184.22.226.205, you need "telnet 184.22.226.205 53" (a space, not a colon).
