Hi DFlyers,
I'm studying in an university, where IPv6 is provided. But all IPv6
addresses are directly and automatically distributed from the shcool's
routers, i.e., each of my machine will get a /128 address via DHCP.(*)
Yesterday, I configured "IPv6 pass-through" for my router (flashed with
DD-WRT), and my Linux boxes inside the LAN can automatically obtain IPv6
configurations, e.g.,
debian-linux> /sbin/ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.234 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 2001:da8:8000:6440::1188 prefixlen 128 scopeid 0x0<global>
inet6 fe80::49a6:fb37:128a:a30b prefixlen 64 scopeid 0x20<link>
ether fc:aa:14:dc:35:1a txqueuelen 1000 (Ethernet)
However, I cannot make my DFly box with IPv6 automatically configured.
Here is my related settings in "/etc/rc.conf"(**):
ifconfig_em0="inet 192.168.1.237 netmask 255.255.255.0"
defaultrouter="192.168.1.1"
ipv6_enable="YES"
ipv6_network_interfaces="em0"
ipv6_ifconfig_em0="DHCP"

dfly> ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

ether 08:00:27:91:44:74
media: Ethernet autoselect <rxpause> (1000baseT <full-duplex>)
How could I make DFly to automatically configure IPv6? Thanks a lot.
(*) Some time ago, I tried to configure my DD-WRT router with IPv6
prefix delegation in order to enable IPv6 for my LAN, but in no vein.
Now I found that this configuration was not supported by the school.
(**) I also tried without 'ipv6_ifconfig_em0="DHCP"', but the results
were the same.
Cheers,
