How to assign a gateway to an alias with multiwan configured?

[Aitor]

Hello, I´ve just configured Pfsense with 2 WAN´s and it´s working OK!.

Some employees have been getting problems when they try to access to some banks webpages.
I´ve been also using Zentyal distro with other clients and that issue I was able to fix it setting WAN1 or WAN2 gateway to the objects (aliases) on Multiwan rules.

Does anyone know how can I create on Pfsense specific rules to aliases to use always WAN1 or WAN2?

I would like also define groups of aliases to be redirected to such WAN to control departments at office.

Any help will be appreciated.

Thank you in advance.
