Forward traffic to 2 different servers using same port

Hi,
i need some help on this. We have a set of 5 public IP (e.g. 197.22.150-197.22.150.5) and we want to redirect https traffic to 2 different servers, depending on the source IP.
If https traffic goes to 197.22.150.2(which is also the WAN interface of UTM), UTM9 forwards traffic to server1 [192.168.2.100]
if https traffic goes to 197.22.150.3, UTM9 forwards traffic to server2 [192.168.2.101]
The https ports cannot be changed since they are system hardcoded.

Configure the IP 197.22.150.3/32 as additional IP adress for interface WAN (Interfaces -> Additional Addresses).

Then create 2 DNAT rules (Network Protection -> NAT -> NAT):

Source: Any
Service: HTTPS
Destination: WAN (Address)
Change Destination To: Server1
And the service to: 
Automatic Firewall rule: yes

and

Source: Any
Service: HTTPS
Destination: WAN Additional IP (Address)
Change Destination To: Server2
And the service to: 
Automatic Firewall rule: yes

...depending on the source IP.

FWIW, you are actually referring to the (external) destination IP.
