Extend IP subnet from main to node

Max.V · 2023-01-02T02:26:02.692Z

I have 2 MV-1000. The main site has 192.168.0 and the node has 192.168.8. and they are connected correctly on a site to site connection.

I am trying to see if it is possible to have the following.

DHCP range on main DHCP range on node
192.168.0.2-100 192.168.0.102-200
gateway 192.168.0.1 192.168.0.101
So normal internet traffic on main will go through 0.1 and from node will go out through 0.101.

Is that possible? I know I can restrict the DHCP ranges on both sides but then, will it work seamlessly when I connect the site-to-site connection?

Thanks.

The two routers using site-to-site must use different network segments. If you want them both to use 192.168.0.x at all, then you can set it to

main site: 192.168.0.1/25
node: 192.168.0.128/25

You need to change this in LuCI → Network → Interfaces → LAN. mask is 255.255.255.128, IP address is 192.168.0.1 and 192.168.0.128.
In addition, you will have to manually add these segments to the site-to-site to ensure they are accessible to each other.
