Don't rememember if this is true or not, but I thought I once saw something
were Firewall 1 did over a 100 mbits with dual ATM adapters. I am thinking
I saw this back in a Sept 96 Data Comm blurb. I need to see if I can
I do know of some testing where an Enterprise 3000 was connected
to a pair of Ultras. The 3000 had an OC-12 along with one of the Ultras.
The other Ultra had an OC-3 in it. Together, the Ultras pushed about
through the 3000. Not too bad!!!
