Good evening,

I am using Airtel 4G sim in Huawei 5G CPE Pro, 5g cpe pro is running in bridge mode and it is connected to a Archer C7.

Airtel/Jio and Vi in some places are issuing IPv6 addresses to their LTE users but they only issue a /64 IPv6 block. The problem with this is, Archer C7 can not redistribute IPv6 address from this /64 block to the clients that are connected to it.

There are some workarounds to this problem but I haven't been able to get them to work on OpenWRT and the stock firmware refuses to fetch a IPv6 address for itself. :/

If I put the 5G cpe pro out of bridge mode(i.e. In Router mode) and put archer c7 in AP mode, Then IPv6 works fine. So That means, the 5G cpe pro is configured to handle this case correctly. In this scenario, The clients don't have the full /64 block but atleast they have IPv6 connectivity.



So, My question is,

Is it possible to get airtel to give me a /48 block instead of a /64 block? Who should I even contact for this? I have already tried googling for this but I couldn't find anyone who has tried this before. :/

I really really like IPv6 and want it to work. So any help in getting even basic IPv6 connectivity(i.e. even a /128 for clients) or any way I can get a /48 from airtel is much appreciated.
 
@ishanjain28 - Hope you are doing good 😊 Thought of checking if you have been able to use your CPE PRO for getting Jio 5G (only IP6 and/64) to hand out addresses to your clients if you put a router (Ubiquity in my case) in between.
