This is a very interesting question!
We absolutely need some documentation on this, as I'm sure that it is a
I don't know if there is a prepared solution for this or if you'll have
to add a firewall rule.
I just tested, and being connected to a LAN port or to the AP of my
LibreMesh router directly connected via its WAN port to my ISP router, I
can ping other devices connected directly to the ISP router.
I tested this both with and without the OpenWrt firewall package selected.
I suppose this is what you do not want, correct?
The easiest solution I can think of is:
* find out the IPv4 of your home gateway (likely 192.168.0.1 or
* from this IPv4, find the subnet of your home network: take the gateway
IP, replace the rightmost field by a zero digit and append a "/24"
(usually either 192.168.0.0/24 or 192.168.1.0/24)
* add this line in the middle of the /etc/rc.local file in the router
directly connected to the ISP, before the "exit 0" line:
iptables -I FORWARD -d your_network_subnet -j REJECT
for example, in my case my gateway router has IP 192.168.0.1 and I added:
iptables -I FORWARD -d 192.168.0.0/24 -j REJECT
If anyone has a more elegant solution, please share!
