I administer several firewalls and would like a simple client server program where I could set up the server app to listen on a selected port. And then "ping" it with the client from outside the firewall to check that the firewall is configured ok.
I'm quite sure that such a program exists out there but I'm not using the right search words I guess....
I'm not looking for a advanced network monitoring/analyzing software just a small client server test app.
Ove.
