SSL tunnel no internet access

Hello,

We would need a specific user to connect SSL tunnel client and access internet troughtout the sophos so that he can have the public Ip from the company.

I've created an SSL VPN and set the tunnel access as "Use as default gateway", created and assigned a group on the tunnel where user is included, and also created a rule VPN to WAN including tt specific user. Not sure why but he cannot access internet,

Any tips?

thanks in advance
