Connect SONOFF Zigbee bridge PRO to HA via MQTT

Hello,
I’m trying to find solution to my connection problem w/o success.
The configuration is:
My son has a remote country house. I installed tasmota32-zbbrdgpro.bin firmware on SONOFF zigbee bridge pro. It works great! Now I can see MQTT messages from my zigbee devices from country house. But I do not know how can I display those messages overview.
I should add that I use 4G mobile network, and I have no access to SONOFF bridge from the HA machine.
Has any one any idea, what should I do to display those values in HA?
With best regards, Alexei

It’s a bit confusing what you are asking. You say that you have MQTT messages from the country house, but you also write about your 4G network and having no access. There’s documentation about MQTT here MQTT - Home Assistant

If that doesn’t help you should explain better what the issue is and how the networks are set up and talking to each other.

Sorry, I was not clear enough.
At country house I use 4G/LTE bridge to have access to internet via mobile network. Actually I share internet from my mobile phone. I can access internet sites from country house fully. But I can not have access to country house from my local flat, where I have HA server installed.
So, I configured SONOFF bridge to send MQTT messages to HA server. I can see those messages in HA moscitto server. But that’s all. I can not see info from country house zigbee sensors on ‘overview’ window.

To clarify my country house issue: I looked in my smartphone “about phone” and see, that phone IP address is: 10.166.229.227. It means that It is behind my provider fire wall.
