Title: Wireguard IPv6 support
Post by: FrenchFries on August 23, 2020, 11:27:09 PM
Dear all,

Does OPNSense wireguard support IPv6? The default documentation does tell about IPv6 in Wireguard, only IPv4.

I am planning to use a Roadwarrior scenario. If the client has a public IPv6 assigned by ISP, IPv6 routing may take precedence over IPv4 routing if Wireguard only offers IPv4. Therefore, Wireguard needs to support IPv6.

Do I miss something or IPv6 is needed in Wireguard?

How to configure IPv6 in Wireguard? Can I choose any /64 within my delegated /48 subnet?

Kind regards,
