My problem is supposed to be very easy and very common, but I am having some difficulties to get it solved
Anyway, here my situation :
- A :One FTTH router configured to work on 188.8.131.52/24 (firmware untouched)
- B : Archer C7 using openwrt (want it to be configured under 192.168.0.1/24) and connected to one of the LAN ports of router A
- C : Archer C7 using openwrt (want it to be configured under 192.168.2.1/24 and connected to one of the LAN ports of router A
The idea is to have two separate networks and avoid any communication between networks behind B& C.
I am stuck in the very first step of configuration : B is connected to A and address is 192.168.1.99. When i change the LAN config of router B to us 192.168.0.xxx instead of 192.168.1.xxx, I can't access router B anymore.
Any help would be appreciated (if my double NAT strategy isn't the best, please let me know )
