Coming into our building we have our ISPs router, then a Layer2 switch and off this 3 ASAs (1 core and 2 for projects)
We have 2 external IP address pools. The primary 1.1.1.1 /29 can be used by any ASA on the layer2 switch, the secondary pool 2.2.2.2 /28 is forwarded from the ISP router to 1.1.1.2 the IP address of our core ASA.
The issue we have now is that we wish to use a few of the secondary external IPs on the other ASAs. As these are for projects the IPs could vary from time to time (or even daily), so contacting the ISP to redirect individual IPs would be annoying. Is it possible to redirect an incoming external IP back out to another external IP?
For example:
ASA1 on 1.1.1.2
ASA2 on 1.1.1.3
IP 2.2.2.3 is forwarded from the ISP router to 1.1.1.2 and then that ASA redirects to 1.1.1.3
Hopefully makes sense and im sure its easy enough, but I just cant think it through today.
