Firewall on WDS repeater

Installing and Using OpenWrt Network and Wireless Configuration
1

I have a WDS wifi repeater set up following the user guide, with a separate SSID from the upstream AP (an ISP router, that doesn't have much to configure). What I want to do now is install adblock-fast on the repeater, and have it work. I have it installed right now, but as I understand everything is on the LAN interface so nothing really goes through the firewall. How can I do that, do I set up a separate interface and use that network, or something else?

2

have the repeater act as a router, where the LAN subnet differs from the upstream router's LAN subnet.

(in openwrt) wifi -> scan -> join (the upstream wifi)
put the new connection in the wan firewall zone.

3

How do I find out the upstream LAN subnet? Do I then go to interfaces > lan then set the IPV4 address, the netmask, or the gateway?

4

check the IP on any device connected to the upstream router.

ipconfig on the upstream router shows

   IPv4 Address. . . . . . . . . . . : 192.168.1.8
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.254

for the repeater

   IPv4 Address. . . . . . . . . . . : 192.168.1.114
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1

What should I change?

in the repeater's /etc/config/network file, change the LAN side IP from 192.168.1.1 to 192.168.2.1, save & reboot.

might want to reset it 1st though, to get rid of the WDS stuff.
