I am working on firewall rules to allow only office 365 when using WAN-2. My Failover is WAN-2 and my network has 3 different VLAN's Main, Client, Crew. All traffic is allowed when using my WAN-1 and when WAN-1 goes down Failover need to be active. WAN-1 allow all the traffic. WAN-2(Failover) allow Mian and block Client, Crew. Main should have only access to Office 365 to send emails and block everything else. WAN-1, WAN-2 use different Public IP. Any help will be appreciated to achieve the above task. Regards.
