Technical Tip: FortiGate traffic not passing between VLANs in Azure

The User traffic is internal, coming from VlanA to VlanB in Azure Cloud

IPV4 Policy:

config firewall policy
   edit <id>
        set name "VlanA-B"
        set uuid xxxxxxx-c238-51f0-4931-xxxxx
        set srcintf "VlanA"
        set dstintf "VlanB"
        set action accept
        set srcaddr "all"
        set dstaddr "all"
        set schedule "always"
        set service "ALL"
   next
end

Reverse policy as per the traffic requirement:

config firewall policy
   edit <id>
        set name "VlanB-A"
        set uuid xxxxxxx-c238-51f0-4931-xxxxx
        set srcintf "VlanB"
        set dstintf "VlanA"
        set action accept
        set srcaddr "all"
        set dstaddr "all"
        set schedule "always"
        set service "ALL"
   next
end

If policies are correct and the sniffer is visible, traffic is going out from the correct outgoing interface.

Make sure the settings below are enabled on the Azure side:

Enable: IP Forwarding
