I have a web server on our inside network (10.15.20.20) that I'd like to have receive responses from a /29 block of external IP addresses within my outside interface's IP block. So basically I'd like any web traffic that hits 18.104.22.168/29 automatically get translated/redirected from the outside to 10.15.20.20. Is this possible?
I can get it to work with a 1-to-1 Static NAT translated/redirected to 10.15.20.20. But I can't seem to get that /29 to translate to the inside address. I've tried Dynamic Policy NAT, Dynamic NAT, with access list config attempts, but it just doesn't want to take.
I'm hearing rumblings that it's not possible, to which I'd be surprised as this is possible on other vendor's firewalls.
I attached my config with clear examples of what might be a futile attempt :)
Any thoughts would be appreciated.
