Greetings,

Before somebody shoots me down on it: I know that ipfw_divert() is
not suitable for IPv6 packets.

So, to the point. This code:

struct sockaddr_in6 addr6;
struct in6_addr ip6_any = IN6ADDR_ANY_INIT;

sin = socket(PF_INET6, SOCK_RAW, IPPROTO_DIVERT);
if (sin == -1)
errx(1, "Unable to create sin socket.");
if (sin > fdmax)
fdmax = sin;

addr6.sin6_family = AF_INET6;
addr6.sin6_addr = ip6_any;
addr6.sin6_port = htons(8669);

if (bind(sin, (struct sockaddr *) &addr6, sizeof(addr6)) == -1)
errx(1, "Unable to bind incoming divert socket: %s",
strerror(errno));

compiles and run fine, but it gives me this in the lsof output:

nat6to4d 67887 root 3u IPv6 0xc8b05000 0t0 HOPOPTS *:*

HOPOPTS is "0" according to /etc/protocols. Making everything IPv4,
it gives this:

nat6to4d 67899 root 3u IPv4 0xc865421c 0t0 DIVERT *:8669

which is what I expected. So why doesn't this get displayed for the
IPv6 sockets?

Edwin
