Figure 50-2 Security Appliance as Firewall with Mobility Advantage Proxy and MMP Inspection
In Figure 50-2, the ASA performs static NAT by translating the Cisco UMA server 10.1.1.2 IP address
to 192.0.2.140.
Figure 50-3 shows deployment scenario 2, where the ASA functions as the TLS proxy only and does not
function as the corporate firewall. In this scenario, the ASA and the corporate firewall are performing
NAT. The corporate firewall will not be able to predict which client from the Internet needs to connect
to the corporate Cisco UMA server. Therefore, to support this deployment, you can take the following
actions:
• Set up a NAT rule for inbound traffic that translates the destination IP address 192.0.2.41 to
172.16.27.41.
• Set up an interface PAT rule for inbound traffic translating the source IP address of every packet so
that the corporate firewall does not need to open up a wildcard pinhole. The Cisco UMA server
receives packets with the source IP address 192.0.12.183.
hostname(config)# object network obj-0.0.0.0-01
hostname(config-network-object)# subnet 0.0.0.0 0.0.0.0
hostname(config-network-object)# nat (outside,inside) dynamic 192.0.2.183
See Chapter 30, “Configuring Network Object NAT” and Chapter 31, “Configuring Twice NAT” for
information.
