 The following error is printed when net.inet6.ipsec6.debug is set to 1:
 
 Jun 18 20:19:23 orion kernel: ipsec6_output_tunnel: family mismatched between inner and outer, spi=156253021
 Jun 18 20:19:23 orion kernel: [ip6_output:549] (ipsec): error code 47
 
 The relevant lines of code are:
 
 --- ipsec_output.c begins here ---
 if (isr->sav->sah->saidx.src.sa.sa_family != AF_INET6) {
                         ipseclog((LOG_ERR, "%s: family mismatched between " "inner and outer, spi=%u\n", __func__,
                             ntohl(isr->sav->spi)));
                         V_ipsec6stat.ips_out_inval++;
                         error = EAFNOSUPPORT;
                         goto bad;
                 }
 --- ipsec_output.c ends here ---
 
 I will be looking further in to this.
