vpn portal without client

Hello friends,

One of our subsidary company needs to have a vpn. Being only about 20 users, preferably clientless vpn is thought for.

Colleague doing some tests for it said the clientless vpn does not have ip address for clients.

It only can support bookmarks that can be configured in it. Is that true?

If that is true, how does it then perform communication for clients when connected?

its on a fortigate 300D running 6.0.x.

Any help will be appreciated.
