I'm installing a fwsm ( multiple security contexts) where the inside interfaces (Scada, Meters, etc) are being protected from Corporate Users. I need to be able to manage from the outside interface, or from the admin context routed from the outside, or shared vlan configuration using multiple contexts. The management systems are located on the outside(Corporate Side)were Cisco Works, VMS , Sylog Servers are located. A site to site VPN would resolve this issue, but isn't there an easier way to perform the same functions since this is an FWSM configuration. If not, what are my limitations when it comes to security level. Does the FWSM only resond to the inside interface security level 0 or any interface except the outside interface security level 100?
