I presume you have the two ports in passive/IDS mode.

In that case it is 0%. However, it is always possible for someone to
accidentally change the policy from passive to inline. If this occurs,
the G would attempt to forward packets around your firewall.

That being said, it is often not a problem in practice as you would
typically use taps or a read-only SPAN port to get the packets from the
network. So, even if the G did begin to forward packets from an
accidental policy change, they would have nowhere to go.

Is there something unique about your environment that makes your
situation more complicated?

What is the probability for Proventia G400/2000 to be bypassed if one
port was connected to a segment located after the firewall, and another
port was connected to a segment located before the same firewall? 

 

If the probability for that is 0%, do you have any official document
that can prove that?
