I have a Fortigate with 2 ISP connections, and 2 firewall policies.
Firewall Policy 1 - to send traffic from internal LAN to ISP A (ID 6)
Firewall Policy 2 - to send traffic from internal LAN to ISP B (ID 12)
Right now Fortigate seems to always select Policy2/ISP B, even if I change the sequence of the policies.
The only way I can get it to use ISP A, is to disable the port for ISP B.
I tried creating a static route to use ISP A, but that creates a whole different issue. Certain computers cannot connect to the internet and Windows troubleshooter points to DNS issue, while some computers have no problems at all. The few computers that had this problem were Windows 7. Not sure if that's coincidence.
So my question is, is there another way for Fortigate to prioritize one Firewall Policy over the other?
