Hello guys i am doing sourcefire POC can anyone please guide me on the following

I have 5585 with source fire hardware module

Below is the topology after putting ASA 5585 {as of now there is no asa In between}

Plz check attachment



Core-1:
interface GigabitEthernet1/3
description  Link to s-rl-ns-dat-1
ip address 10.200.0.1 255.255.255.252
ip flow egress
ip policy route-map NK_CO_INET
ip ospf network point-to-point
end

CORE-2:
interface GigabitEthernet1/5
description  Link to s-rl-ns-dat-2
ip address 10.200.0.69 255.255.255.252
ip policy route-map NK_CO_INET
ip ospf network point-to-point
wrr-queue cos-map 2 2 3 6 7
 wrr-queue cos-map 3 1 4
 snmp ifindex persist
end

DAT-1:
interface GigabitEthernet1/1/7
description * Link to s-rl-ns-cor-1
no switchport
ip address 10.200.0.2 255.255.255.252
ip ospf network point-to-point
ip ospf cost 5
mls qos trust dscp
end

DAT-2:
interface GigabitEthernet2/1/7
description * Link to s-rl-ns-cor-2
no switchport
ip address 10.200.0.70 255.255.255.252
ip policy route-map NK_CO_INET
ip ospf network point-to-point
mls qos trust dscp
end

Please provide your  suggestion how can we put ASA in transparent mode as shown in image .

yes that i can understand about redirecting and sourcefire stuff but Client is not ready to change subnet in that case how can we achieve this ?
