Cannot access anything from SSL VPN

Hi guys,

I have just setup SSL VPN with Duo security proxy server. The VPN is working fine, I can log using Sophos Connect, get my Duo confirmation and end up connected with an IP address from the pool.

But then, I can't seem to access anything. My first step is simply to ping the UTM (ping is allowed through ICM) but it does not answer on any interfaces.

Here is a few screens from my actual setup (this is for testing purpose, not the final required setup) :

If you need anything else, just ask me.

Thank you for your help.
