Thanks for pointing out my mistake!  I've tested now using udp and hey! it works!

Now I can make some progress.

I'm planning to install software on my VPS, which requires incoming UDP

My iptables is set to allow incoming udp on that port, but it remains 
closed to the outside world.

I've set up a simple listener on port 10000, then tested using a web 
service for port checking, and I've tested using telnet from two other 
locations.

"Unable to connect to remote host: Connection time out", says telnet.

Have I omitted to do something I should have done?

Ian.


Telnet does TCP connections. For UDP you have to use nc/netcat in simple
UDP mode on the client side and in listening UDP mode on the server
side, type some text and see if you can read it on the server side.
