Problem configuring VLANs on WRT32X

Installing and Using OpenWrt Network and Wireless Configuration
#1

Hello,

I am trying to setup via ssh the VLANs for my ISP on a WRT32X and I read a lot of threads here but I'm not succeeding.

The VLANs my ISP has in bridge mode are:

Internet: id 6, priority 1
IPTV: id 2, priority 4

When I do reset the router and I do the welcome setup and enter the username and password for pppoe, internet works correctly but the TV does not, network file is automatically configured like this:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config interface 'lan'
        option type 'bridge'
        option ifname 'eth1'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth0'
        option proto 'pppoe'
        option disabled '0'
        option username 'adslppp@telefonicanetpa'
        option password 'adslppp'

config interface 'wan6'
        option ifname 'eth0'
        option proto 'dhcpv6'
        option disabled '0'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '0 1 2 3 6'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '4 5'

I tried a lot of configurations and I invested a lot of hours in order to add VLAN id 2 for IPTV but nothing worked and I don't know what else to do.

For more information

  • The TV decoder is on Port labelled with 4 (I think it is port 0?)
  • ISP told me that TV decoder needs VLAN 2 and internet connection too to connect external services like Netflix, I don't know if this is relevant like that the port where the decoder is has VLAN 2 + VLAN 6 or something like this, or if this is not possible and there is not solution for me.

Thank you in advance.

EDIT: for more information

I redone all the process and I'm going to detail it here for more information:

ONT

Do reset to ISP ONT and go to WAN setup, this is the default:

vlan1
vlan1967×226 7.8 KB

  • ID 3: VOIP
  • ID 2: IPTV
  • ID 6: Internet

Delete ID 2 and ID 6 WAN services

vlan2
vlan2969×168 6.57 KB

Add ID 2 bridge mode for IPTV:

vlan4

Is it good checking Allow as IGMP Multicast Source?

vlan5

vlan6
vlan6971×192 7.41 KB

Add ID 6 bridge mode for Internet:

vlan8

vlan9

vlan10
vlan10971×218 7.86 KB

LAN configuration:

vlan11
vlan111013×723 28.7 KB

Reboot ONT

WRT32X

Do reset and connect it to the configured ONT

Welcome setup, PPPoE

I leave the VLAN ID empty

vlan12
vlan12718×646 58.2 KB

If I put VLAN ID 6 it says that there is no connection:

vlan13
vlan13728×766 68.8 KB

Welcome setup done

vlan14
vlan14771×786 100 KB

Check internet connection setup

Connect via ssh and check /etc/config/network

        option ipaddr '127.0.0.1'

        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth0'
        option disabled '0'
        option proto 'pppoe'
        option username 'adslppp@telefonicanetpa'
        option password 'adslppp'

config interface 'wan6'
        option ifname 'eth0'
        option proto 'dhcpv6'
        option disabled '0'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '0 1 2 3 6'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '4 5'

You are not using VLAN 6 in that setup; if you can connect to the internet with that configuration, then your comment about VLAN 6 and 2 does not apply here.

Also, you have not configured any IPTV connection. But you do not mention any decoder, and you definitely do not need IPTV for Netflix.

Are you sure the ISP device is configured completely as a bridge?

This is the ISP device configuration is a semibridge:

vlan
vlan790×255 91 KB

veip0.2 is VOIP and it is fine on the ISP device (I don't need it on the wrt32x).

About IPTV, I need to know what to put in the network file because I tried a lot of things with no luck, the image shows how the Welcome setup configures it by default when I set on Welcome setup the user/pass for PPPoE.

The decoder is on wrt32x port 4 (I think it is port 0) and it needs IPTV connection but it has Netflix installed and needs internet connection too.

Can you tell me what to put on the network file to configure the VLANs despite it is working internet connection like this? When I can I will check the configuration of the ISP device to check the bridge configuration.

Thank you.

You ISP uses one VLAN for internet connection, one for IPTV, and another one for VoIP. According to the link you sent me privately (https://www.adslzone.net/foro/asus.164/es-posible-hacer-full-bridge-router-askey-movistar.475302/#post-3241882), the ONT is in a semi-bridge configuration, where all three VLANs are mirrored on the LAN port, untagged.

IMHO, that is a very weird way to do things, but I guess it is all that can be done with that ONT...

Notice how the guide you followed requires to change the LAN address on the OpenWrt router to 192.168.2.1, but yours is still configured on 192.168.1.1; please, do that change first. The next step is to add a route on the router. It looks like you do not have to fiddle with VLANs at all.

You are right, it is a weird way but it is all that can be done with that ONT.

I hadn't seen the steps you mentioned, I was following guides to configure de VLANs but you are right, I followed the steps in that guide (it's the linked next post) only adding the route on the router and now it is working fine internet and IPTV on every port of the router.

I don't know why are so much guides for this concrete ISP and ONT configuring VLANs when it is much easier this way.

Thank you very much for your help.
