Freenet6: spreading IPv6 addresses to the LAN

Hi. I've have my FreeBSD 4.8-RELEASE firewall successfully configured
with Freenet6, with a /48 prefix. I can ping6 other sites:
# ping6 -c 3 www2.at.freebsd.org
PING6(56=40+8+8 bytes) 3ffe:b80:3:75b7::2 -->
2001:628:402:1:202:a5ff:fefb:40cb
16 bytes from 2001:628:402:1:202:a5ff:fefb:40cb, icmp_seq=0 hlim=50 time=516.289 ms
16 bytes from 2001:628:402:1:202:a5ff:fefb:40cb, icmp_seq=1 hlim=50 time=547.238 ms
16 bytes from 2001:628:402:1:202:a5ff:fefb:40cb, icmp_seq=2 hlim=50 time=575.88ms
--- www2.at.freebsd.org ping6 statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/std-dev = 516.289/546.469/575.880/24.334 ms
What I would like to do now is use autoconfiguration to allocate ipv6
addresses to other hosts on the lan. It isn't happening.
Below is a selection of (hopefully) relevant information about my setup:
# tspc -v

This is the information for the host I want to autoconfigure. It is
also FreeBSD 4.8-RELEASE:
$ grep ipv6 rc.conf

$ ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

ether 00:02:b3:23:bc:fe
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
Because it is an internal-only machine, it doesn't have any firewalling
stuff in the kernel. I can ping6 its own link-local address, and the
link-local address of the interface on the firewall that is connected
to my LAN.
"rtsol fxp0" doesn't seem to do anything on this machine - I still have
the link-local as my only inet6 address for that interface.
I don't think I need any other information, do I? I have attached the
kernel config files for both hosts to this email.
What do people think? I am missing something really obvious here?
TIA,
Bill.
