SSLVPN - Set default gateway ip

Hello,

I wonder is it possible to set up one default gateway for all ssl-vpn users (tunel-mode), at this time when user get ip for example 10.10.10.2, the gateway on PC is next ip - 10.10.10.3. Next user for example get 10.10.10.40, then his gateway on PC is 10.10.10.41.

I want to set up for all SSL-VPN users default gateway - 10.10.10.1. I cant find any information about that. Is it possible?

I set up static ip addresses using Radius.

I have Fortigate 60E.
