I have plenty of firewall rules to test.
I'm currently using WinSSHD & Udp Test tool to listen on
destination Win 2012 servers & from the source servers,
used MS Portquery to test.
Portquery is fine in that it allows me to specify a range
of Tcp+Udp ports.
However, at destination end, WinSSHD & Udp Test tool
can only bind or listen to one port at a time so this is not
productive if I have thousands of ports to test.
Is there a tool that could verify that firewall rules have been
permitted correctly without the need to set up a listener at
the destination (as currently the Apps team haven't got the
time to install their actual apps yet) & I need to test in
Alternatively, suggest a couple of freeware that could be set
to listen on a range of ports (or can be selected number of
ports separated by say, commas) for Windows 2008/2012
