More than 2 vlans problem

Hello friends,
I think i found some kind of bug.
For some reason i am able to create only two vlans working properly, but the other vlans does not ping each other
I have created several VLans, but only two work.

So the vlan 1 is working ok,
The VLAN 10 is working ok
Other vlans does not work for some reason,
Does anybody have a similar problem?
Is there some hardware limitations over vlan?
Thanks
Pucci

You will need a managed switch, and it needs to be properly configured. Do you have one and is it configured??

And let’s see your complete config in text form.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

How exactly are you testing this? Wired, wireless? Do you have a managed switch? Is it properly configured?

Is it a correct statement to say that 192.168.1.1 is a gateway upstream of the OpenWrt device? Does it have a static route for each of the other networks?

Two openwrt connected together over wired cable on lan port.
It is properly configured on both ends just like you teached me how to do it.

Usually i dont configure routing because the dhcp itselt configure the routing for the clients, as there is only one dhcp server
i did this test with fixed ip just to try to understand why it does not work.

Did you configure the upstream device with the VLANs, too?

DHCP has nothing to do with routing. But if the upstream device has the DHCP servers for each VLAN, that is sufficient.

I'm still not clear as to how exactly you are testing this. And for that matter, what the purpose is of this second OpenWrt device.

  • Can you explain what you want this OpenWrt router to do?
  • Please create a system topology diagram so we can understand how everything is connected and from where each of the tests is performed.
  • Please show us the configuration of the upstream OpenWrt device.

Is there any openwrt specialist paid support?
I would like to learn more..
Also if it is a bug, you could learn more about the product in different enviroments.
You can access over Anydesk and i can show you eveerything? How about that?

No. I mean, you could offer to pay someone, but that would be an agreement between you and the person who takes you up on that offer. OpenWrt doesn't have any such service and would not be involved or responsible for any agreements you might make with other people.

If you're trying to learn how to solve the issue you've described, you're in the right place. But you need to answer the questions I've asked and provide sufficient detail such that I/we can understand the full context. We can't read minds.

I don't think that there is a bug here. The problem is likely either configuration related or an issue of understanding what can/should happen in a given environment.

That's not the way I offer help. I do everything here on the forum. If you can provide the things I asked, I should hopefully be able to help you solve your issue.

hi, this stanza looks weird to me. my vlan config looks much simpler and different. were you upgrading from an older owrt version keeping config maybe?

8021q is meant for single ports, not for bridges.

So this is a problem? I'm not creating any of these manually, I am using the luci to create everything

@psherman do you agree this is a problem?

I don't think this is a problem.

I tryed with another router, they are all conected together.
None of them are pinging each other

OMG I SOLVED IT.

AFTER ALMOST GIVING UP.
There was a router in the middle of the two that i forgot.
When you start using vlans you have to understand that every device in the middle of the communication have to be configured for that vlan, otherwise it will drop it.

@psherman I would like to buy you a coffee for your time, or donate to openwrt.

Thank you man!
