I would like to just have the second ISP give me MORE bandwidth to outside world. Mostly I see people talking about Dual WAN for redundancy, or to partition certain traffic to use a certain WAN. I would just like to have the internal network use up all of WAN1 bandwidth, and then start using Wan2 bandwidth, so overall I have more bandwidth. I am using firmware 4.2.2 on a 200B.200B running 4.2 is 802.3ad capable. Depending on how your ISP is bringing services to you, check 4.2 admin guide for ' link aggregation' to aggregate interfaces to increase bandwidth available. First warning: aggregate interfaces must all connect to the same next-hop routing destination. With 2 different ISPs I cannot figure out how that could be performed regards,

ORIGINAL: ede_pfau I think it' s much simpler: just configure 2 default routes to your 2 ISPs with equal distance and priority. Then, the Fortigate will distribute internet (outgoing) traffic evenly. No need for policy routing or anything. If you want to you can look it up in the FortiOS Handbook, " ECMP" (equal cost multiple paths" routing).not exactly Ede, I understand from cmberry' s post is that he don' t want balancing in any way. He would add bandwidth from the second WAN when the first one became exhausted or something like that. ECMP is about balancing between wans, not for adding more bandwith to the existent one.
Link aggregation is nice but will not work with 2 different ISPs.yup, it' s nice, but with several constraints to deploy it regards, A.

I read about it in the FortiOS Handbook and in the web config HELP, both list it as showing up in Router > Static > Static Route, but NOT in my 200B 4.2.2. It should have a link after the word " delete" , but there is nothing there, Hmmm. Can someone else running 4.2.2 confirm its missing or moved, or am I crazy?
conf sys settings set v4-ecmp-mode usage-based endinstead.
yep, confirmed. Version: Fortigate-50B v4.0,build0291,100824 (MR2 Patch 2)Ok, thanks for looking. I did as you suggested: config system settings set v4-ecmp-mode {source-ip-based | usage-based | weight-based} end I added spillover threshold for each interface, 1500 kbps for one and 6000 kbps for another, and I' ll see how it goes. By the way, both interfaces are working to the outside world, so now it' s a matter of me tweaking it so they are utilized in a way that I have maximum bandwidth. I wonder if it' s a bug that the web config does not show ECMP, or if it' s by design? In terms of Firewall policies, do I need to double all of my policies from WAN1 for WAN2? Right now I have a policy that does Internal -> Wan1, with various UTM features. I also added a Internal -> Wan2 manually. But with ECMP and static routes with same distance and priority, is this still necessary?
