The cable Internet at my parent's house died and in order for IPv6 to work with the 4G internet connection, I've just created a NAT66 source NAT rule on my parent's #OPNsense This feels very wrong, but since the 4G connection only gets a /64 prefix, I can't do NPTv6, so this is all I can do. But at least it works. 🫣IPv4 is only NATed by the Cable and 4G routers, and WAN failover is taken care of by Gateway Groups.
