Redirect local traffic to another WAN

Hello,

I am new in Fortigate. Sorry for this newbie question.

Here we have 2 links (WAN 1 is the second and WAN 2 is the main), the Fortigate model is 90D.

So, all internal computers are using WAN 2 to access the Internet, but I am trying to redirect internal traffic for a given IP, on a specific port always out for WAN 1.

For example: One computer here using WAN 2 to access the Internet, need to access the server 200.100.200.5, on port 1521 and the outgoing need to be WAN 1, always, how can I do this redirect on Fortigate?

I appreciate any help!

Regards,

Ricardo
