Ideally I would like to place an ASA 5510 in line between three devices on the same subnet and have the traffic between them inspected.
For example the network 10.10.10.x
Eth0/0 would have input coming from 10.10.10.1
Eth0/1 would have input coming from 10.10.10.20
Eth 0/2 would have input coming from 10.10.10.30
Leaving the management port with 10.10.10.10
Currently I have the ASA setup as a Transparent Firewall based on the following example:http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a008089f467.shtml From this it only looks like two connections on the same subnet are allowed, but I am new to this so I am not quite sure.
With the Transparent Firewall configuration I am also experiencing difficulty accessing the ASDM application.
Any help would be greatly appreciated.
