Re: iACS have cwbping?

In addition some so called 'intelligent' firewall modules which decide that traffic on this or that port doesn't conform to traffic patterns the module knows and thus shuts you down.

Currently the cisco 'fire at will' (firepower) module is on my 'most hated' listed. So far it has been confirmed to terminate PTF downloads (claiming they are oversized PDFs LOL!) as well as POWERHA traffic. I have only one customer who purchased that module who is still using it.

True, to a point. Depends on how likely your shop is to start locking
down connections by port. Firewall stuff. We don't do that internally.

Then again there are those who like to have multiple exits out of the
system. This is why some people still used pagers with modems instead of
network connectivity.

I think you're correct in trying your end-to-end test. But if you "just
know" that it should work but it doesn't then having that local test in
your bag of tools is something to see if the network guy tightened things
up too much.
