I follow link below for setting up RPi access point with a bridge
Setting up a Raspberry Pi as an access point - the easy way
I install cloudstack manager which has cloudbr0 bridge
Now I want to have access point but I need NAT to isolate it from router
So the topology should look like below
What should I change for such configuration?
RPi
wifi ┌──────bridge──────┐ wired wan
mobile-phone <.~.~.~> │(wlan0) br0 (eth0)│ <-------> router <-----> INTERNET
\ | / DHCP-server
(dhcp 192.168.4.x (dhcp 192.168.50.x 192.168.50.1
from RPi) from router)
