The client is getting an IP from the IP range I setup for the VPN.
I'm quite new with the fortigate, i'm guessing there is a CLI from which i can get the output, otherwise i can grab some screens, what would you need ? I'm guessing screens of the policies and SSL settings.
Everything I see seems correct. The only things I guess I can think of, just because I can't see it, is verify the interfaces on the ipv4 policy are ssl.root to the correct interface the server is on.
As well, verify in the SSL Settings that the group VPN_GIMI is assigned to the correct portal.
Edit - I guess just for the sake of verifying everything. What are the objects SSL_ACCESS and GIMI_RANGE_SSL_VPN for? Based on the SSL Settings it's assigning IPs based on the default object SSLVPN_TUNNEL_ADDR1
Actually thinking about it a bit more, that may be the problem. If you remove SSL_ACCESS from the IP Pools(or remove the default one and add SSL_ACCESS to the ipv4 policy) it should work.
