If you get “Your browser has a real working IPV6 address but is avoiding using it.” on, this is normal as IPv4 has higher metric than IPv6 ULA. ipv6 route add dst-address=2000::/3 gateway=ether1 Choose the right gateway depending on where the IPv6 connectivity is coming from.If the route does not exist, add a route. Make sure you have an IPv6 route that goes to the gateway on where the IPv6 connectivity is coming from. ipv6 firewall nat add action=masquerade chain=srcnat ipsec-policy=out,none out-interface=ether1 Either out-interface-list=WAN or out-interface=ether1 depending on where the IPv6 connectivity is coming from. This is equivalent to IPv4 private network addressing. ipv6 nd set interface=bridgeĪdd a Unique Local Address. By default, Neighbor Discovery is enabled for all interfaces, but it’s better to run it just at LAN.

Set the Neighbor Discovery to the correct interface. So we need to perform NAT66 or masquerade to be able to access the IPv6 internet when you only have a single IPv6 address. Yes, I know NAT is bad, really bad when we are talking about IPv6, but since your provider only provides a single IPv6 address, only the router has IPv6 connectivity, and the rest of your devices doesn’t.

You have an IPv6 connectivity in your WAN or you use a VPN, but sadly it only provides /128, requiring you to do NAT.
