Guest Wifi, no access to internet

zhuco · June 6, 2022, 8:33am

Hello,
Is the first time I use openwrt on my DAP-2610.
I have follow this guide, but the clients connected on guest signal do not access on on internet.
The error diplayed on browser is "ERR_CONNECTION:REFUSED".
Can you help me?

Try removing the default gateway (192.168.50.1) from the br-guest interface?

viniribeirossa · June 6, 2022, 9:04am

Remove this line. Reload firewall and try

zhuco · June 6, 2022, 9:13am

Hello,
thank you, rule removed but the problem is the same!
No internet!

zhuco · June 6, 2022, 9:15am

I try but the problem do not change!

viniribeirossa · June 6, 2022, 9:19am

Remove this line too. If you want to use br-lan gateway, put the interface firewall in lan, but that would not make sense for your guest rules. Remove this line from gateway 192.168.50.1 and leave default

network.guest.gateway='192.168.50.1'

viniribeirossa · June 6, 2022, 9:25am

and RELOAD NETWORK and TRY

trendy · June 6, 2022, 9:38am

Have you followed the correct guide?
In the guide the uplink is via wan interface, but it is evident that you have a dumbAP and the gateway is on the lan interface. There is a separate guide for that.

zhuco · June 6, 2022, 9:53am

I have found the correct configuration.
I removed this roule:
network.guest.gateway='192.168.50.1' and set the netmask 192.168.50.255
and changed this:
firewall.guest_dhcp.src_port='68'
in this
firewall.guest_dhcp.src_port='67-68'

and reboot.
The guest have internet!

Thank you all!!!

zhuco · June 6, 2022, 10:25am

I Am very disappointed!
It worked briefly, after I have the same problem came back....

viniribeirossa · June 6, 2022, 12:12pm

Remove netmask and leave default. I restarted the network and try

eduperez · June 6, 2022, 12:33pm

The guide says:

uci set network.guest="interface"
uci set network.guest.proto="static"
uci set network.guest.device="br-guest"
uci set network.guest.ipaddr="192.168.3.1"
uci set network.guest.netmask="255.255.255.0"

But your config says:

network.guest_dev=device
network.guest_dev.type='bridge'
network.guest_dev.name='br-guest'
network.guest=interface
network.guest.proto='static'
network.guest.device='br-guest'
network.guest.netmask='255.255.255.0'
network.guest.ipaddr='192.168.60.1'
network.guest.dns='1.1.1.1' '8.8.8.8'
network.guest.gateway='192.168.50.1'

I would start with a basic working configuration, follow the guide without adding anything unneeded, and make sure it works before adding more changes.

zhuco · June 6, 2022, 1:47pm

I have used this guide:

# Configure network uci -q delete network.guest_dev uci set network.guest_dev="device" uci set network.guest_dev.type="bridge" uci set network.guest_dev.name="br-guest" uci -q delete network.guest uci set network.guest="interface" uci set network.guest.proto="static" uci set network.guest.device="br-guest" uci set network.guest.ipaddr="192.168.3.1" uci set network.guest.netmask="255.255.255.0" uci commit network /etc/init.d/network restart

zhuco · June 6, 2022, 1:48pm

Sorry, witch is the correct guide???

zhuco · June 6, 2022, 1:49pm

I have changed only the IP!
On 162.168.3.1 I have the voip!

eduperez · June 7, 2022, 1:36pm

There is an extra "gateway" parameter (and I must confess I looked no further).

zhuco · June 7, 2022, 1:54pm

The internet gateway is: 192.168.50.1
You can see on the list.
network.lan.gateway='192.168.50.1'
and this:
network.guest.gateway='192.168.50.1'
but if this is set or no do not change the result because the guest do not access on internet.

In the pass I usa dd-wrt and I remeber is necessary insert per setup of firewall to permitt the bridging from lan to guest on openwrt this setup where is???

zhuco · June 8, 2022, 10:17am

Hello,
this morning I reset the AP to default, and used only the command in this guide.
The guest do not access to internet!

AashishAS · June 8, 2022, 10:44am

Ok so now I think I got what is the problem, the ap doesn't have a wan network because you are using it as a dumb ap and it is only forwarding data via lan, so the firewall rules don't work because you have specified a wan interface in them to forward data from lan but such network doesn't exist.

Now you have 2 choices

Create a wan network on the dumb ap which will
then get the forwarded data from the guest
interface and hence get internet connectivity, this
could be tested by specifying a dummy wan
which uses your main router as dhcp gateway.
On your main router create a guest interface and
then on your ap use the interface of the main
router as gateway address.

trendy · June 8, 2022, 10:47am

You keep following the wrong guide. There is specific guide for your case.
