multiple wan public addresses port forwarding issue

Hello,

I am using a fortigate device:

wan connection interface:99.99.99.33

i have been given 2 additional addresses from my isp

99.99.99.198

99.99.99.199

1-i am not sure where i can add these 2 ip addresses as additional wan addresses in forti, i added them in ip pools

2- i have a webserver in dmz 192.168.100.150 listening on port 80

i need to create a rule that make login from the outside to this webserver from one of the additonal wan addresses with port 8080.

example when i type from outside: http://99.99.99.198:8080 it will show the web interface of the webserver on my dmz. please write me the steps because what i did didnt work.

This is my configuration

​

Policy And Projects > Ip pools > created 2 ip pool objects

name: ip_pool_1

type: overload

external ip range: 99.99.99.198 - 99.99.99.198

second one name ip_pool_2 external ip range 99.99.99.199- 99.99.99.199

​

then i created a virtual ip

name: web in

external ip address /range: 99.99.99.198-99.99.99.198

mapped ip address/range 192.168.100.150- 192.168.100.150

port forwarding enabled

protocol:tcp

external service port 8080-8080

map to port 80-80

​

then policy & objects > ipv4 policy > new policy

name: to_device

incoming interface: wan1

outgoing interface: dmz

source: all

destination: wen in ( the ip i created before)

schdeule: always

service: http

action: accept

nat: enabled ( also tried to disable it same thing)

ip pool configuration: use outgoing interface address

enable this policy: enabled

​

How do i solve this? Help!!

thanks
