Jio Airfiber outdoor unit (CPE) connected to Openwrt instead of Jio Router

[adinetech]

@MrGordon I tried Route and Bridge mode, Both of them were able to do IPv6 PD, but It doesn't give Internet access (I tried it on openwrt and macbook and with Custom IPv6 DNS as well). Do you have any idea?

Currently, the ODU is connected with my Macbook on Route mode.

@adinetech Does connectivity over IPv4 atleast work? I see there is an IPv4 address set.

 

[adinetech]

Unfortunately. It didn't work as well and it's the IPv4 provided by the DHCP of the ODU, It seems CLAT is handled by the ODU. It would look spam if I attach all screenshots here.

 

[MrGordon]

Yeah that's how most 5G routers do it, they do CLAT on their end and just assign a local IPv4 address. Mine does the same.

It's interesting why there is no connectivity. Did you try cloning the mac address of your IDU by any chance, just in case they have some sort of check like that.

 

[adinetech]

I'm yet to try that, I noticed that the DNS lookup works with both Route and Bridge on the ODU but the ping/traceroute (ping6/traceroute6) didn't.

After some search, I confirmed that it's not "easy" to do on macbook, so I connected to the openwrt and then used the IDU's "WAN" mac, It didn't work. I tried using the ODU's device mac and the result was same. Something is preventing

I would be "less" sad if the IDU was not locked down upto this extend, I can't even turn off it's WiFI. I found that the ODU has a USB C (Type C) but I have no idea what it could be.

Edit: I'm giving up after days of efforts. I failed.

I noticed that the Ethernet link is often becoming 10M, BSNL fiber was down for almost 10 min today and I noticed everything was slow, download and uploads were limited to ~8.5 Mbps. This is weird, 100M Ethernet link would be fine but 10M is "not fine!"

@MrGordon As you said, I could spend 20k on the a 5G Equipment (found from the other thread) and then pay for Jio's 599 Postpaid plan. They claim to be "unlimited" and I don't see any fair usage policy (FUP) for this plan. I'll decide it within 3 months, If you have better and cheaper solutions. Please let me know.

Quess what? I restarted it and the internet is gone. No link between ODU and IDU (and then, just restarted the IDU and ODU individually and it didn't help as well). I thought cellular means 24/7 internet but seems not true with Jio's Airfiber service
