I would like to seek advices regarding to Cisco Firewall Module [WS-SVC-FWM-1] and IPv6 network.
At this moment, our server farm is capable to support IPv4/IPv6 network, and our servers are starting to use both to serve our end-users.
My questions are:
1. Does Cisco Firewall Module [WS-SVC-FWM-1] supporting IPv6 network?
2. If not supported, is there any alternative to filter inbound/outbound IPv6 traffic to our server farm?

It seems this support was introduced later than the code you are running.
(look at the "Core IP Enhancements" section)
