Switching bridge to router, to avoid interaction between the AP clients and the relais.

Change 'lan' from bridge to wireless

uci del network.lan.type uci del network.lan.ifname uci set wireless.@wifi-iface[0].network=lan uci set network.lan.ipaddr=192.168.1.1 uci set network.lan.netmask=255.255.255.0

Add 'wan' interface (wired to the relay node)

uci set network.wan=interface uci set network.wan.ifname=eth0 uci set network.wan.proto=static uci set network.wan.ipaddr=192.168.2.1 uci set network.wan.netmask=255.255.255.0 uci set network.wan.ip6addr=fd64:2c08:9fa7:19::1/64

Update firewall (TODO)

/etc/init.d/firewall disable

Keep radvd configured for advertising on 'lan' (see above)

Reconfigure babel to use 'wan'

echo "package babeld

config general option local_server '33123'

config interface 'wan'

config interface 'lan' option ignore 'true'

config filter option type 'redistribute' option local 'true' option ip fd64:2c08:9fa7:19::/64 option action 'allow'

config filter option type 'redistribute' option local 'true' option ip '192.168.1.0/16' option action 'deny' " | uci import

Modify /etc/config/firewall:


# Leave unchanged: defaults, lan zone

config zone
        option name             wan
        option network          'wan'
        option input            ACCEPT

        option forward          REJECT
        option masq             0
        option mtu_fix          1

config forwarding
        option src              lan
        option dest             wan

# Add:
