Hi @tex_er605_oc200 

Thanks for posting in our business forum.

PVID = 11, so this profile on this port should include Untagged VLAN 11.

Replug the client into the portWAN/LAN1 after the configs are saved. (You should see "Configuring" on the router or any Omada devices if you make a change. Wait for it to turn into "Connected". Then the parameters should be effective.)

PC should get VLAN 11 IP address then.

Hi,

I have this setup for my ER605:

 

Port 1: WAN

Port 2: VLAN2

Port 3: Open

Port 4,5: VLAN1

 

Port 1 is connected to the modem in passthrough mode.

Port 2 is directly connected to a PC acting as a server, running ubuntu.

Port 3 was open, and now connected to OC200.

Port 4 -> Unmanaged Switch -> Managed Switch -> Wireless AP

Port 5 -> Wireless AP

 

Everything was working fine and Port 1 was isolated through VLAN to the rest of the ports.

 

After connecting the OC200 to port3, I tried setting up the VLANs the way I had set up earlier.

But I am not able to get the ip address on my server PC anymore.

 

This is what I did:

Settings -> Wired Network -> LAN -> Create New Lan

 

In The Profile:

 

PS: I tried with setting Untagged Network and Tagged Network setting to various permutations, but no dice)

 

Then I go to my ER605 and enable the PVID to 11

 

 

It was working all fine before adding OC200. Not sure what else I need to do.

Computer is supposed to run fine. Run another computer and check if that computer can get the VLAN 11 IP. It should work without a problem.

Just set the port and set the PVID, the PC should get the IP from the ER605.

Nothing else is required.

Thanks for the help.

Can confirm the IP is assigned on a different PC. I was testing the config on a MAC with an ethernet USB-C adaptor, and that doesn't seem to take the IP. Connecting to a PC worked.

 

Then this is not an issue with the router or controller. VLAN works. Might be the adapter issue or the driver.

I tried connecting to an ubuntu server PC and the IP is correctly assigned. But it is not getting access to internet. The server also shows up on the client list on the controller for a few seconds and then it disappears.

When I do 'ping 8.8.8.8', I am getting "destination host unreachable".

I connected the same cable back to a windows PC and everything works, but it's not working on ubuntu and mac. This is the same server that had been working flawlessly for almost a year now with ER605 VLAN before OC200 was connected.

I also tried to ping the gateway and still get the same icmp error.

Please advise.

What is the ICMP error you get?

If you ping the gateway IP and gets errors, you might wanna take a look at your ipconfigs.

You probably did not set the gateway. If it is DHCP, DHCP would inform the gateway IP in the DHCP assignment. DHCP client-server interaction - IBM

Either Wireshark and see if anything is wrong with DHCP, or you should check what's wrong with the network adapter on the PC and the VM NIC settings.

Everything is correct. I get the IP assigned and DHCP server and gateway IP also looks correct. Tried connecting a dumb tplink switch and the ubuntu desktop through that, that also didn't work.

ifconfig result:

inet 192.168.2.2 netmask 255.255.255.0 broadcast 192.168.2.255

Default Route: 192.168.2.1

DNS: 192.168.2.1

I am not gonna help you troubleshoot on the Linux computer or its system to find out the reason why does not get an IP address. Don't expect me to do so. This is not part of my job to help you beyond our product.

I cannot remote because it is not my job either. You should find the technical support during working hours but they don't provide help on Linux.

You probably should ask this on Ubuntu or Linux Reddit.

Just based on the screenshots you provided, I have examined your settings before and they look good. Setting them up properly would work. And you answered before that just this Ubuntu PC does not work, which also supports my belief that your VLAN is good. It seems to be a problem with the Linux. So I don't have a suggestion for this because it is not my job to help you with your Linux. Not to mention there is ZERO information you provided to me about the Linux config.

Here's my question, will a regular computer work with the VLAN on ER605? If it works but your Linux, you should find help from the Linux community as we have pinpointed the problem is only on the Linux.

If it doesn't work, give me the Wireshark result so I can check. Your network diagram and your VLAN settings. You've configured it so you know what screenshots should be sent.
