How do I verify network endpoint connectivity.

ShepEd Hi, Sorry no, I wasn't able to find any way of testing this.  When Companies say "Ensure that devices can reach necessary endpoints through the firewall. "; and give you protocols or wildcard addresses, that does not seem to be possible as far as I can tell.  The only thing I found useful is to send these details to the managers of each of our Firewalls if there is a problem and hope they can find something.  What I also found with our firewalls is often traffic is blocked outside the rules inside the firewall and is within configuration of the firewalls so isn't logged which makes that process hit and miss too, so one firewall manager could verify the traffic passed through their firewall, then the next firewall has no record of it ever arriving. If you discover anything, I'd love to know.  good luck.
