There is still a point that isn't clear for me : should i advertise my
LAN prefix on the rest of the network and if yes isn't there a specific
option i should set on the RA so that the hosts do not renumber ?
Because, if i don't advertise in any way this new prefixe how will the
routing protocols be able to find my new_lan ?

in fact i have the following architecture : 

  network ---- my_router ---- my_lan
    |
    |
   DHCP

the hosts behind the router in my new LAN were before directly connected
to the network and the DHCP configures them. If is simply enable the
IPv4 forwarding and set the corresponding rules in my netfilter conf,
will the hosts behave normally, or do i need to configure them in static
mode with my_router as GW ? (All hosts/servers are in the same IPv4
network, 152.81.x.x). As the only need i have for my IPv4 connection is
for apt, setting up a NAT wouldn't cause damage (it isn't a production
network, it's only ta make a few tests around IPv6).

And for IPv6, i think i'll have to set more complex rules, ie forward
everything from the native network to the LAN (but not the sig traffic)
and in the other way forward the traffic which source is my network to
the native network (again only the traffic, not the sig) ?
