Run the net tests and observe:

    ipforwarding_v4: [10.451720s] Passed.
    ipforwarding_v6: [17.491396s] Passed.
[38.940463s]

Failed test cases:
    t_forwarding:ipforwarding_fastforward_v4,
    t_forwarding:ipforwarding_fastforward_v6,
    t_forwarding:ipforwarding_fragment_v4, t_forwarding:ipforwarding_misc

I think this has more to do with libexec/httpd and rump than network forwarding: the tests which pass, test using ping rather than try to get a file from a webserver.

All errors are of the form:

tc-so:Executing command [ env LD_PRELOAD=/usr/lib/librumphijack.so /usr/libexec/httpd -P ./.__httpd.pid -i 10.0.2.2 -b -s /tmp/atf-run.Vu1QEW ]
tc-se:Fail: incorrect exit status: 1, expected: 0
