Fortigate Wan Load balacing

[iBite]

Hi everyone! 

I'm new here!!

i'm 19 years, and i love working with fortigate. But i have a problem... A company i work for want to have a dual wan connection. On wan 1 there is the first isp, with virtual ip addresses, so on that wan connection there is the mail server hosted, also the vpn portal. Then you have the wan 2 connection, thats the speedy connection. But when i enable the wan 2 connection then i cannot ping anymore to wan 1 public ip, also i cannot connect to the webmail that's another ip from isp 1 wan on wan1. so the incoming traffic is not working anymore.

Many thanks!!!

Hi, you can check the routing table which routes are used.

Probably the default route is changed when you plug in wan 2.

You can make this work with ECMP and a route prio for the speedy link.

scenario 3a, 3b (also possible via web gui)

if that is already configured it could be a bug depending on which version you are running. (i know there was 1 in 5.2.3)
