It might only be accepting connections from certain source IP
addresses.

I've run the AA server and afterwards grepped the output of the
command you've suggested. Here are the interesting ports:

udp 0 0 *:1716 *:*

udp 1648 0 [isp url address]:1717 *:*

udp 0 0 *:14200 *:*

Maybe instead of my URL address provided by my ISP there should be an
IP?

No, just that's a feature of the output of telnet. You can tell telnet
to output numeric addresses instead by adding the '-n' option.

Anyway, the output tells you that that you have processes listening on
ports 1716 and 14200 (all interfaces) and port 1717 (external interface
only). All of the above use UDP, so telnet won't be able to connect to
them. You mentioned running nmap also ... did you do so with the '-sU'
option?

Not at the moment of writing that message, but after adding -sU the
results are:

# nmap -v -sU [isp url]
