I have a cisco ASA 5505 (ver 8.0.4) that currently has one IP address on the outside interface, 10.1.1.1. This is used for all communication with the outside world.
I want to add a second IP to this interface, 172.16.0.1, that will only get used for traffic to a specific remote IP (18.104.22.168)
That is, if a packet is for 22.214.171.124 it goes out the outside interface with a source IP of 172.16.0.1; any other traffic goes out the outside interface with a source IP of 10.1.1.1
The current config:
interface Vlan2 nameif outside security-level 0 ip address 10.1.1.1 255.255.255.0 ! interface Ethernet0/0 switchport access vlan 2 ! global (outside) 1 interface route outside 0.0.0.0 0.0.0.0 10.1.1.1 1
How can I add this second IP and make the required routing tweaks?
