YazFi - NAT to guest wifi

[r000t]

Hi,

I have some IoT devices on guest Wi-fi, which only accept connection if SRC IP belongs to the same network (e.g., Yeelight smart lights).
I know it is possible to add custom IPTABLES commands to

/jffs/addons/YazFi.d/userscripts.d/custom.sh

, but I am not that skilled at IPTABLES and afraid of breaking things.

Can you please advise which rules do I need to add so that the trafiic from the main Wi-fi will be NATed to the guest Wi-fi in a "one way to guest" mode?

#!/bin/sh
#iptables -I YazFiFORWARD -i wl0.1 -o br0 -d 10.0.1.5 -j ACCEPT
iptables -t nat -A POSTROUTING -o wl0.1 -s 10.0.1.5 -j MASQUERADE

This worked for me where 10.0.1.5 - my Home Assistant server inside the home network. Yeelight's local mode now works with the guest network as intended.
