Struggles with 4G EE network connection

[rivimey]

I have been provided with an EE72E dongle to connect to the internet via WiFi which seems to work fine when I connect to the internet via the donge's WiFi directly from my Macbook. However my need is to connect my Linux-based firewall/router for the house to the internet, rather than just one computer, so I have connected a USB Wifi dongle to the router, and established a WiFi connection from the router to the EE dongle.

Theoretically this should be sufficient, IMO. However any outgoing packets sent to the WiFi interface on the router just disappear - none are ever replied to, whether DNS query or anything else. I do have a default route set to use the WiFi connection, and I am monitoring the packets using "tshark -i wlx50*****fc8".

What is going wrong? How can I make this all work?

Sorry, I had picked up the wrong mobile router. Now put the right 1 in I should have said:

Login to your MBB router at http://192.168.1.1 with the admin password found under the battery cover. Then look at Status > Connected devices.

You are misunderstanding the WiFi connection's addressing:

I don't think so! It's just that we speak a diff tech lingo. However I did get confused between your USB WiFi dongle attached to your other router & the 4GEE WiFi router (which is not a dongle at all).

So the upshot is that 192.168.1.1 is the IP addy of the 4GEE WiFi router & 192.168.1.227 is the IP addy of your other router, via its  USB WiFi dongle.

I do understand how packets & NAT work.

IPv4 should work between the 4GEE WiFi router & the other router.
