I got banned!
For me it’s ministry of defence as well. 25.120.21x.x
The /29 subnet is an implementation bug; 3GPP data bearers are point-to-point links to the gateway. With slightly complicated routing rules, the only unreachable host would be the one with the same IP as yours i.e. 25.33.186.52.Exactly, it's only a /29 so the number of unreachable hosts are just 8 or so. Plus it's all UK Defence department's so not somewhere I'd want to reach. 🤣🤣

And the other 7 IPs in the same /29 subnet because of the implementation peculiarity on Linux-based devices.
But its not always /29, right now its a /25 and an appropriate route for the rest of the /25 subnet also got created.
Code:56.85.35.128 * 255.255.255.128 U 20 0 0 eth0.2
Traceroute over this connection looks weird, they seem to be blocking ICMP or it doesn't work at all. I cannot even ping the gateway as shown.
By the way, what's the 10.0.1.0/24 subnet for? And is IPv6 disabled on the dongle?
I'm interested in getting a outdoor LTE CPE. @varkey can you please guide me on that.As far as the setup is concerned, this is not through a JioFi dongle (although the setup itself shouldn't matter, cause even @Nikhil Sharma is seeing the same behaviour). I use an outdoor LTE CPE device with the JIo SIM inserted, in bridge mode (with IP passthrough enabled) and the WAN interface on my router is configured in DHCP client mode. So it gets the IP address (Jio WAN) directly over DHCP.
I can't really access the device physically at the moment as I am accessing it remotely plus being an outdoor device can't really go and take out the SIM 😉
The passthrough works similar to how its described here -- Manual:Interface/LTE - MikroTik Wiki
So I don't think it actually does a PPP connection, and appears to be something based on QMI/MBIM. Since it doesn't do PPP, I guess it is possible for QMI/MBIM to support non ppp type setups? PPP as you rightly said doesn't care of the subnet, and the gateway can be from any subnet for that matter.
That's the LTE CPE's management subnet. Since the device is in bridge/IP passthrough mode, I had to assign an IP address from the management subnet to the same interface to be able to access the management UI.
Yep, IPv6 is disabled on the LTE device.
