Is it possible to setup an Active/Active FWSM Configuration where there is a shared interface between both Active contexts.
There will be 2 x 6506's with a FWSM each. I want to have an Active Context on each FWSM in the 6506's. And I want to make a shared interface between these active/active contexts across both 6506's.
You are right.
As I said the decision to pick Context is made on the "Destination address" defined in a NAT statement.
For your outgoing traffic (from vlan 20) hitting internet. It would be practically impossible to define NAT statements for internet Hosts.
One option here would be to introduce two VRFs between vlan 20 and the two FWSM contexts.
