Is support of RFC 5549 possible in Freebsd? Hi, I have thought a bit about this, and have some ideas how implement this. In general we can install into the kernel routes that has IPv6 address as gateway for IPv4 (currently this is not allowed by default, but it is easy to allow). So, as a routing daemon developer you can use generic API to install routes where RTAX_GATEWAY is IPv6 address. Then we need to modify ip_forward, ip_output, ip_tryforward to correctly handle such routes. layer2 output routines should already correctly handle IPv4 packets that are going trough the IPv6 gateway and it will use ND6 lookup code to obtain Layer2 addresses. The most complex it seems will the modification of ip_tryforward code, since it is optimized for IPv4 and doesn't have enough room for extending. With such changes IPv6 only router should be able to do IPv4 forwarding. The problems that come to mind are inability to correctly send ICMP messages, since there are no IPv4 addresses that can be used as IPv4 source, and how existing programs will handle such routes when they will appear in a routing socket. -- WBR, Andrey V.
