Re: Assymetric Routing / Statefull Inspection Firewall

If you are asking for stateful filtering for a firewall that sees only
one-way conversation, it does not exist and cannot exist, by definition.

If you are asking for some way for firewall A that sees only inbound 
packets and firewall B that sees only outbound packets to communicate said 
information - I suggest mirror port on a switch.

Otherwise, as long as firewall sees both incoming and outgoing packets, 
why would it care what happens later at your border routers?
