This can cause problems if you are using stateful filtering.
Products such as PIX, however, can work in a redundant fashion.
This means if one PIX falls over, the other PIX takes over it's
states.
However, firewalls are not for high-tech load balancing. Look
at Cisco LocalDirector and Distributed Director, and F5 Networks
BIG/ip and 3DNS products if you want stateful failover of
layer 7 information.
