One VIP address to multiple internal IP's to different ports

Hi!

I have found similar post as below but I cannot make it working.

https://forum.fortinet.com/tm.aspx?m=103076

I have Public IP 176.95.2.141 and want to use it to multiple Inside addresses

So I created VIP addresses

Name: out-In-A

External IP 176.95.2.141

Mapped IP: 192.168.1.1

Port fowarding: Exter port 1111 Map to port 1111

Name: out-In-B

External IP 176.95.2.141

Mapped IP: 192.168.1.2

Port fowarding: Exter port 8080 Map to port 8080

Then I get this error "address names and virtual ip names cannot be the same"

Thanks for looking into this.
