I'm connecting to Freenet (and other IPv6 providers) from a few FreeBSD
servers. The tunnels work well, and rtadvd is correctly configuring other
hosts on the LAN, but I'm not too sure about how to configure other
interfaces on the IPv6 router itself. For example, this is the tunnel
interface on one of the machines:
kirk@gopher:~$ ifconfig gif0 inet6
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 208.162.254.126 --> 64.71.128.82
inet6 fe80::2d0:b7ff:fe4e:11c2%gif0 prefixlen 64 scopeid 0x7
inet6 2001:470:1f00:ffff::37d --> 2001:470:1f00:ffff::37c prefixlen 128
...and this is the LAN interface on the same machine.
kirk@gopher:~$ ifconfig fxp1 inet6
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::203:47ff:feb1:d892%fxp1 prefixlen 64 scopeid 0x2
inet6 2001:470:1f00:546:: prefixlen 64 anycast
Note that the host portion of the address is all zero. Also, whenever I
connect to any machine on the LAN, the source IP is 2001:470:1f00:ffff::37d,
the local IPv6 address of the tunnel. I have two basic questions:
1) What should my address be on fxp1? How do I configure that automatically
(i.e., edit rtadvd.conf)?
2) Why isn't my router using the address of the LAN interface for the source
IP on outgoing connections to machines on the LAN?
