To enable dual-stack-mode, all SSL-VPN policies must be configured with IPv4 and IPv6.

Hello, when dual-stack is configured on the fortigate and you connect with Forticlient 7.0.7 with "Enable Dual-stack IPv4/IPv6 address". Do you get ONLY an IPv6 address?. Also, once connected. In example, if you have an SSLVPN zone to Internet zone Firewall policy. How does that work? For IPv4 you would need NAT, but for IPv6. You would not need NAT.  Can you have one policy for IPv4 (NAT'ing) and different policy for IPv6 not NAT'ing?
