Flint 2 no Internet from ONT modem

Routers
1

I bought the GL.Inet MT6000 Flint 2 to replace my old Fritzbox. Now I have a problem with the setup: the interface is connected, but no Internet connection is available. I entered the data in the PPOE basic mask, and the data is correct because it was taken from the functioning Fritzbox. I have also set IPv6 to native. I already tried rebooting.

Here is some additional information that may be important:

Fiber optic internet FTTH

No public IPv4 address

IPv4 via DSLite

I use my ISP's ONT modem (Genexis FiberTwist-P3410B)

My ISP is citykom (local internet provider from​ Germany)

Maybe someone from this community can help me solve this problem. Thanks in advance. ​

I would try this (in order from most to less common):

  • Check if you need to configure any VLAN Tag for internet service.
  • Some ISPs check ONT MAC address to allow connection, so if it is the case, you also would need to clone MAC address from ONT.
  • Some ISPs require specific MTU for internet connections.

Hey thanks for the reply. To your suggrstions:

  1. My ISPs customer service told me that i don't have to configure any VLAN. In my previous Routers settings there was also no VLAN configured.
  2. I already tried to clone my FritzBox's MAC, sadly without success.
  3. I don't know about that, I tried some standard ones (1480 and 1492) but these didn't work. I also didnt find any in my FritzBox's WebUI vor the manual sheet Form my ISP.

Currently I use my Fritzbox in “bridge mode” (ipv6 passthrough or how its called) but I really don't love this method, even if it is working.

Can you make a tracert to www.google.com and post results? Do you have an assigned IP in flint2 status Ethernet section?

Hi

Could you clarify which internet access method your ISP provides — PPPoE or IPv6 DS-Lite?

If it’s the latter, it is currently not supported through the GL UI.
Please refer to the steps below to configure it via LuCI instead:

Hey,

thanks a lot for the suggestion. It worked and I now have full internet access with my Flint 2 Router via my ONT device.

I had to install the pkg via SSH, but still connected via PPoE. It auto created the DSLite dual and WAN6_4 DHCPv6 interfaces needed for AFTR (would only work automatic since I had no AFTR-credentials).

The only downside is, that the GUI still shows that I dont have Internet connection, which tbh. isn't a big deal.

Thanks for anyone who contributed to this thread and helped me find the solution.
