Guest Wifi on Access Point

This doesn't sound right. What is the output of uci export network; uci export dhcp; uci export firewall from the access point ?

per un access point
modifica:

config forwarding
         option dest 'wan'
         option src 'Guest' 

change:

config interface 'Guest'
         option proto 'static'
         option netmask '255.255.255.0'
         list dns '8.8.8.8'
         list dns '1.1.1.1'
         option ipaddr '192.168.2.1' 

It is already the same as you requested. Also changing the config forwarding to WAN makes NO difference

then I leave you in the hands of:

lleachii

who is much more competent than myself ...

Try this:

uci delete firewall.Guest.masq
uci set firewall.lan.masq='1'
uci delete network.Guest.gateway
uci delete network.Guest.dns
uci add_list network.lan.dns='1.1.1.1'
uci add_list network.lan.dns='8.8.8.8'
uci set network.lan.gateway='192.168.1.1'
uci commit firewall
uci commit network
service firewall restart
service network restart

Still the same, IP is served but NO internet.
Any other thoughts ?

Remove masquerading from the guest firewall zone. Add it to the lan zone.

If you look at the configuration files posted earlier, you will see that the critical firewall rules are already there. The op has not yet blocked the traffic between subnets, but that will not impact general connectivity.

So what is your problem?

Resolved by changing Masquerading from Guest to LAN.
Thanks to everyone for help, especially Psherman

Very good
Please see also from my post

Now that the Guest Wifi works, how do I stop the clients from accessing the local LAN on subnet 192.168.1.

I have enable the client to client communications, but this is not stopping the access to the local 192.168.1 subnet

config rule 'guest_private'
        option name 'Drop forward guest zone to private nets'
        option src 'Guest'
        option family 'ipv4'
        option dest '*'

        list proto 'udp'
        list proto 'icmp'

I don't know, however, if the firewall rule I posted to yours works because you have enabled masking to the LAN

my config is

and thanks to:

Thanks for your input. However, I realised that I hadn't setup a firewall rule to Block access to the LAN. Once I setup the rule, it stopped the access to the Local LAN devices.

Great Forum, Thanks to ALL involved !
