Are there any firewall rules at LAN1 or ROUTER? I assume not.
You'll probably need to provide tcpdump (like 'tcpdump -n -vvv -s0 -e
-w tcpdump.log -i ethX icmp6') on both the router and host when you've
a manual and automatic setup. '/sbin/ip -6 r l' on both systems for
both setups would probably also be helpful.
You can send these to me off-list and continue discussion there; we
can report the details back on list when the issue is resolved.

radvd.conf that you posted is OK.
Forwarding needs to be enabled on the router if you want to access
You also need to configure 2001:7a8:6d7a:4::4/64,
2001:7a8:6d7a:c::4/64, and the default manually on the router.
