I know from experience FortiNet FortiGate does offer dual-stack SSL-VPN, in combination with their FortiClient SSL-VPN software. I haven't found an official statement yet, but the details can be found using the configuration documentation: https://docs.fortinet.com/document/fortigate/6.0.0/cookbook/941552/editing-t... christian bretterhofer wrote at 2019-03-10 22:09:
Sorry for a little be off topic query.
I am checking which VPN solutions are IPv6 compatible outside and inside the tunnel and can so transport with any IPv6/IPv4 connection IPv6/IPv4 internal to then tunnel
Maybe somebody made such tests already and can point me to it. What i found so far:
Citrix SSL VPN ( seems to have only partial support) https://support.citrix.com/article/CTX233563 https://www.citrix.com/blogs/2010/07/13/are-citrix-products-ipv6-ready/ so IPv6 / IPv6 not yet supported https://support.citrix.com/article/CTX211780 NetScaler Gateway VPN users are not able to resolve IPv4 DNS when their ISP has IPv6 enabled.
OpenVPN https://community.openvpn.net/openvpn/wiki/IPv6 No complete example found yet.
Wireguard (LINUX only) seems to support it but missing other stuff like hostchecker
