What happens if you do: route add -inet6 -host 2001:4f8:0:2::e -prefixlen 128 ::1 -reject route add -inet6 -host 2001:6c8:2:600::132 -prefixlen 128 ::1 -reject and try again with ftp? Which is the test case I did here locally. Obviously I should try on my gateway rather than on the same machine but as you cannot I'd start with this test. /bz -- Bjoern A.
