How to setup Client Bridged / Client Mode / RelayD and IGMPProxy for OpenWRT / LEDE
# Client Bridged / Client Mode / RelayD and IGMPProxy (It works)
# RelayD is to redirect packages and IGMP is for redirect IGMP packages
# Our network is 192.168.1.0/24
# Steps:
# Configure WAN as static
# We should edit our wan iface and put static IP
uci set network.wan='interface'
uci set network.wan.proto='static'
uci set network.wan.ipaddr='192.168.1.239' # Main Network IP
uci set network.wan.netmask='255.255.255.0'
uci set network.wan.gateway='192.168.1.1' # Main Network Gateway
uci set network.wan.dns='192.168.1.1' # Temporary, to have internet here
# Disable physical WAN
# If we want to avoid conflicts if we connect something by mistake on wan port (we could disable it)
uci del network.wan.ifname
# Put temporarely LAN on another network
uci set network.lan.ipaddr='192.168.11.1' # FAKE IP (recommended to be in another never to be used subnet)
uci set network.lan.netmask='255.255.255.0'
# Now we must change our computer IP to this range to be able to connect to it
# We will get internet using WAN (WiFi) now
uci del network.lan.gateway
uci del network.lan.dns
# 4) Setup Wireless connection Client
uci set wireless.@wifi-iface[-1].device='radio0'
uci set wireless.@wifi-iface[-1].network='wan'
uci set wireless.@wifi-iface[-1].mode='sta'

It's confusing me, that you igmpproxy-config the up/downstream altnet as a C-Class local-subnet, and even one different from your main-subnet 192.168.1.0

We Configure igmpproxy

uci set igmpproxy.@phyint[0].network='wan'
uci set igmpproxy.@phyint[0].altnet='192.168.0.0/24'
uci set igmpproxy.@phyint[1].network='lan'
uci set igmpproxy.@phyint[1].altnet='192.168.0.0/24'

and don't you also have to add the role upstream/downstream?
