Routing website to use specific WAN interface. (RESOLVED)

[GM IT team]

Hi everyone,

I have been having an issue with certain website that use Public IP address for log in. My Pfsense sets Multi-Wan with three interfaces.
The web sever does not really respond properly because Public IP keep switching between three WAN.

Is there any way I can set this website to use only one specific Wan?

Thank you so much for your help
