Mudi GL-E750 doesn't work with Providers with IPv6

Do you use teamviewer? We can do a remote assistant. So it will be easier than you provide log.

I installed teamviewer. I am ready now - for the next three hours. If this is bad for you, please make a proposal for a later date.
How I have to tell you the Teamviewer session ID?

alzhao · 2020-05-13T12:21:44.445Z

Pls pm me. Can we connect your tomorrow morning? It will be my afternoon.

tschaefer · 2020-05-13T12:24:08.947Z

Tomorrow morning in CEST is Ok for me, but I haven’t found the PM-function in this forum. I see my inbox, but I don’t see a button “create message” or something similar.

Click on @alzhao name above his posts, and it’s the blue “Message” button for private message.

Oh interesting, you don’t have that button hmmm. Might be cos you are a new user?

@alzhao Can you start a PM to him?

alzhao · 2020-05-13T14:58:10.331Z

Just did.
Just sent a message

tschaefer · 2020-05-14T07:30:57.788Z

I replied with the teamviewer ID/pw

tschaefer · 2020-05-14T09:58:07.093Z

It works now. Unfortunately I was on lunch. What should I do, if it happens again?
When is IPv6-access possible?

alzhao · 2020-05-14T10:16:47.259Z

When changing from QMI to ttyUSB Internet works. I will check IPV6.

tschaefer · 2020-05-14T10:31:15.407Z

Which USB-port/device should be used?

alzhao · 2020-05-14T10:56:33.309Z

ttyUSB3 is for data and ttyUSB2 is for command

Hello,

I do have exact the same issue here. Could you please provide solution in this thread?

Best regards,

alzhao · 2021-02-22T14:05:36.015Z

Better describe more details. Thread is old. Firmware version also changed.

tschaefer · 2021-02-22T17:52:31.908Z

Despite the latest release 3.105 from 2020-12-07 15:29:22 the problem still persists.
Also with beta 3.201 no success.

Hi there,

in my case the following did help, but I’m noiw facing permanent reconnects (1 Minute-interval):

uci set glipv6.globals.enabled=1
uci commit glipv6.globals.enabled

uci set network.3g.ipv6=1 #enter correct interface-name instead of 3g
uci commit network.3g

edit file /etc/chatscripts/3g.chat:
OK ‘AT+CGDCONT=1,“IPV6”,“$USE_APN”’

Maybe these hints do help you out.

Best regards,

With the firmware version V3.203 - Aug 3, 2021
IPv6 (dualstack) works with Deutsche Telekom, Vodafofone and Telefonica in Germany.
IPv6-only (apn internet.v6.telekom) by Deutsche Telekom still doesn’t work with the mudi.

For the new version I reported it already here:

GL-E750 Version 4.3.8 IPv6 4G LTE, 5G NR, USB modems

Hi, the new version (I did a factory reset to avoid conflicts with old configuration data) does not work with IPv6 properly. “Native” and " Passthrough" don’t work at all. The mode “NAT6” mode works, but that is not the expected behavior. Even the default local addresses are not RFC compliant. (something with dd instead of something out of fd00::/8 ) The old 3.217 was able to run in dualstack mode with (real/public) IPv6 addresses and the natted ipv4 address. Any chance to have working IPv6…

I have got a test firmware. So it worked at least in passthrough mode.
