Can you NAT to a network that is not directly connected to one of your firewall ports?
Firewall Outside 220.127.116.11
Firewall Inside 10.101.1.2
Internal Multilayer Vlan1 10.101.1.1
Internal Multilayer Vlan2 10.101.2.1
Can you NAT incoming traffic for 18.104.22.168 to 10.101.2.1? Assuming there is a route in place on the firewall to the 10.101.2.1 network.
