BGP – Asymmetric Routing Fortigate or when it is the policy

Change the Setup to have two dedicated links from the fortigate to the Edgerouter.

Internal6 and 7 on the Fortigate and eth4 on the edgerouters.

Note to myself Policy blocked the traffic. Needed to change the source interfaces to include i6 and i7.

config firewall policy
