Eth1 vlan 911 tagging for ISP connection

Thu Apr 25, 2024 9:20 pm

Hi,

I am after some guidance.
Basically I am unable to connect my router: MikroTik RB5009UPr+S+IN
to ISP's network.
ISP's requirements:
"You basically need to provision the WAN/Internet interface for IP over Ethernet.
Second requirement is that VLAN tagging needs to be enabled on the interface and set to vlan 911.
Third requirement is that the interface IP needs to be set to DHCP. That way it automatically gets assigned an IP from our DHCP server."

My config (it seems that I cannot get an address from DHCP):

Image
I would appreciate if someone would help me to get my router connected. Thanks

Do you have any firewall rules that might block?

You need to go to IP DHCP client next.....
and select vlan 911 as the interface ( not vlanfiber! )

vlanfibre is a vlan created and set to vlan 911 the only other option I have is Fiber_eth1, I cannot add vlan 911 as you mentioned in DHCP client?
Even when I switch dhcp client up to Fiber_eth1,same issue it does not seem to get and address
Can you advise further? sorry

The 1st requirement is kinda odd: "IP over ethernet". If that mean PPPoE (or perhaps Mikrotik specific EoIP?) that be different story, but I presume they just mean it has VLAN. But step 1 is an odd way to state a requirement.

One thing might help here, is if you can use /tool/torch on the fiber or VLAN, and just see what kinda of packets are flowing over the line and/or what VLAN they appear.

Did you add "vlanfiber" VLAN interface as a LAN in /interface/list?

Yeah I meant WAN. So that's right.

Try the ether1 in torch, to see if you getting any traffic from upstream. The torch above shows your dhcp-client looking for an address on VLAN 911.

Might want to post your config too. In terminal, :export file=config.rsc then download from Files.

Re: Eth1 vlan 911 tagging for ISP connection

Fri Apr 26, 2024 4:33 am

This all looks right. The odd thing is that it does look like the ISP thinks your IP is 10.2.118.106 on VLAN 911.

You're running an older version. And I want to say some version had some bug in dhcp-client around that time.

You may want to download latest stable release, and copy it to the root of Files, then reboot:

Re: Eth1 vlan 911 tagging for ISP connection

Fri Apr 26, 2024 5:06 am

Maybe disable PoE on ether1? e.g. you have this message:
Code: Select all
# poe-out status: short_circuit
Possible that interfering with the traffic, since your not getting anything back (or at least only a few packets).

Can also look at Logs, and see if anything there has errors/warning.

But I'm kinda out of suggestions here. Maybe someone else has an idea here.

Disabled it, rebooted the router - error disappeared

did another torch scan:

I hope someone can help, I raised this with ISP too, will see what they say as I am out of ideas

Re: Eth1 vlan 911 tagging for ISP connection

I supose you can try disabling the "input" firewall filter rule with "drop" and "!LAN" & see if you get a DHCP address after that.
If that works, then you might have to allow DHCP from the VLAN 911 to the firewall to allow it I guess.

And/or, just assign the IP address it's showing torch as an /ip/address for the VLAN. e.g.
/ip/address/add interface=vlanfiber address=10.2.118.106/24
Then see if /ping 10.2.118.1 works from RouterOS Terminal?

Okay, that all I got. I was guessing at the default gateway, and it's unclear why touchthe dst-addr of 10.x.x.x

Is there a modem to reboot? But I think you're going to have to confirm with your ISP the needed settings. As I said, the first step "IP over ethernet" is just pretty vague.

Am I missing PPPoe settings or set up on the router? can they use PPPoe without a username and password? would I have to potentially clone the MAC address of the ISP's router on my Mikrotik router (if that's even possible)? as I assume they would have provided it when I contacted them regarding router set-up...
as I have seen this forum post of someone setting up a tp-link router same provider they seem to have a similar issue https://forums.thinkbroadband.com/fibre ... .html?vc=1

I have contacted the ISP again for clarification and support, but if anyone else has any ideas I would appreciate your support. Thanks

Yeah, they may need to know your MAC address. You can "clone it" but simply entering your old router's MAC address on the ether1 interface, obviously your older router have be unplugged after.

Cloning MAC address of ISP's router did not work, still seems to be doing the same thing where it does not pick up IP from DHCP, still waiting for a response from ISP...

Just and update for anyone who might be experiencing or going through a similar issue, ISP advised that router config seems to be fine they reduced DHCP lease to 5 min and advised to connect Mikrotik router, o have restarted the ONT & Mikrotik router, unfortunately it still appears to be searching for IP address and did not receive one yet 30 minutes later, router will be left plugged in overnight and will see if anything changes by tomorrow...

Asked ISP what further steps will be taken to resolve the issue if this won't fix it, currently waiting for further guidance...

Eventually, the Mikrotik router seemed to pick up the IP from DHCP after ISP reduced the lease time from DHCP to 5 minutes, not entirely sure why it took so long...
