Folks,

I have the following configuration on my server (4.4-STABLE):





tl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 10.0.0.8 netmask 0xffff0000 broadcast 10.0.255.255
        inet6 fe80::280:5fff:fe9f:4047%tl0 prefixlen 64 scopeid 0x1 
        ether 00:80:5f:9f:40:47 
        media: 100baseTX <full-duplex> status: active
        supported media: 10base5/AUI 10base2/BNC 10baseT/UTP <hw-loopback>
none autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex>
10baseT/UTP 100baseTX <hw-loopback>
tl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 3ffe:c00:8034::a00:8 prefixlen 48 
        inet6 fe80::280:5fff:fefe:eeaa%tl1 prefixlen 64 scopeid 0x2 
        inet6 3ffe:c00:8034::80:1 prefixlen 48 
        inet6 3ffe:c00:8034::53:1 prefixlen 48 
        inet6 3ffe:c00:8034::25:1 prefixlen 48 
        ether 00:80:5f:fe:ee:aa 
        media: 10baseT/UTP <full-duplex> status: active
        supported media: 10base5/AUI 10base2/BNC 10baseT/UTP <hw-loopback>
none autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex>
10baseT/UTP 100baseTX <hw-loopback>




As you can see, I have a few IPv6 aliases on my tl1 interface.  Here come
the questions...

(1) I cannot ping6 those aliases from other devices on my LAN, although I
can ping6 those aliases from the local machine.  I also cannot ping6 other
hosts on my LAN from this machine, sourcing the ping6 from an alias address.

(2) I cannot connect to IPv6 virtual servers (defined in Apache's httpd.conf
using 3ffe:c00:8034::80:1) from other machines on my LAN, although I can
from the local machine (using lynx).  Here is a snippet from the httpd.conf:



    <VirtualHost 3ffe:c00:8034::80:1>
    DocumentRoot /usr/local/www/data
    </VirtualHost>


There are other virtual hosts, but their presence doesn't come to bear on
this situation.  This works from the local machine, but not from any other
machine on the LAN.

If more information is needed, I will happily provide.

Anyone want to enlighten me?  Thanks in advance for the help!
