I am configuring a new Cisco ASA 5505 with the security plus license. The customer has a block of ip's from the ISP, the subnet is 255.255.255.240. The client wants certain ranges within a certain subnet to route out using different IP's from the block. Say that 192.168.0-100 needs to be routed out IP 188.8.131.52; however, 192.168.101-200 needs to be routed out IP 184.108.40.206. The interface is setup as 220.127.116.11 255.255.255.240.
