IPv6 aliases on FreeBSD 10

[pepe]

Hello!

I was on vacation for a while and too busy to do anything about this. But
now we've done testing and we're getting nowhere...

Current config is:
        inet6 2001:14b8:1801::2 prefixlen 64
        inet6 2001:14b8:1801::c001 prefixlen 64
        inet6 2001:14b8:1801::3 prefixlen 64
        inet6 2001:14b8:1801::c002 prefixlen 64
        inet6 2001:14b8:1801:1:: prefixlen 64
        inet6 2001:14b8:1801:1::1 prefixlen 64

And from those addresses only first two are working. I also tried adding
aliases with /128 instead of /64, but it changed nothing.
With /128 it worked just the same way. I've used fe80::1%em0 and
2001:14b8:1801::1 as default gw. Both of those work, but
same thing with either gw, only those two addresses work.

Current rc.conf is:
ipv6_activate_all_interfaces="YES"
#ipv6_defaultrouter="2001:14b8:1801::1"
ipv6_defaultrouter="fe80::1%em0"
ifconfig_em0_ipv6="inet6 2001:14b8:1801::c001 prefixlen 64"
ifconfig_em0_alias59="inet6 2001:14b8:1801::2 prefixlen 64"
ifconfig_em0_alias60="inet6 2001:14b8:1801::c002 prefixlen 64"
ifconfig_em0_alias61="inet6 2001:14b8:1801::3 prefixlen 64"
ifconfig_em0_alias62="inet6 2001:14b8:1801:1:: prefixlen 64"
ifconfig_em0_alias63="inet6 2001:14b8:1801:1::1 prefixlen 64"

alias58 is ipv4, so this starts from 59. As you can see I've tried both
gw:n on rc.conf, it changes nothing. And I've tried aliases
with /128 prefix and it changes nothing.

I'm starting to think it's problem on ISP side and not ours. But just to
sure - anyone have any ideas what more to try?
