RouterOS does actively ignore IPv6 address from assigned via LTE Provider

Wed Jan 17, 2024 8:54 pm

Hi,

I am currently using a RB912UAG-2HPnD with a Sierra Wireless Model EM7455 Revision SWI9X30C_02.38.00.00 which works fine, so far.

In my Lab I used it with a Sim Card from "Deutsche Telekom", and everything worked out of the box - public IPv4 and public IPv6 was no Problem, it just ran out of the box.

Now, in the field, I try to set up an O2 Germany Card with the APN internet.eplus.de - or just internet, does not make any dfference.
The APN IP type is set to "auto" so, I hope to get IPv6 as well as IPv4 (on O2 Networks certainly only dynamic CGNAT IP addresses)

Even switching to IPv6 Only does not make RouterOS to accept the assignet IPv6 /64 Network.

When set to auto, the following is logged on the lte topic:

It is clear that mbim got a network and dns servers via ppp and offers it to the system, but the routeros simply ignores it somehow:


[admin@SBC-LTE-Mikrotik] > ipv6/ address/ print 
Flags: D - DYNAMIC; L - LINK-LOCAL
Columns: ADDRESS, INTERFACE, ADVERTISE
#    ADDRESS                       INTERFACE    ADVERTISE
0 DL fe80::6e3b:6bff:fe08:8e/64    bridge       no       
1 DL fe80::c8d7:ecff:feb6:ecb2/64  ipv6-bridge  no       
2 DL fe80::6e3b:6bff:fe08:8f/64    wlan1        no       
3 DL fe80::1e:10ff:fe1f:0/64       lte1         no       
[admin@SBC-LTE-Mikrotik] > 

I disabled all firewall rules which could interfere with the dynamic offering mechanisms used in this context, I tried both APNs (but I doubt that has to do with that, 'cause if I'd use a IPv4 only APN I don't get an IPv6 Address assigned in the Logfile in the first place.


When changing to Telekom again, everything works fine - so it seems to be kinda incompability between O2 and Mikrotik?

Any help is very appreciated!

Cheers

Got the same issue, have you found any solution to get ipv6 working on the lte modem?

Have you tried in "LTE APNs" > "default(or any other name you have)" uncheck "Use Network APN" checkbox?

Got same problem and was able to fix it with this.
