Vodafone Station public ipv6 address is not working

Configuration
1

Hi,
I have an EasyBox router, Vodafone Station,
is it possible to access the homeassistant from outside using an ipv6 address?
No public ipv4 port,
only ipv6 are available, but they don’t work when I’m trying to access from another network, e.g. o2,

from the router:

Name: homeassistant
IPv4: 192.168.0.243
IPv6: 2a02:908:3711:xxxx::43f8

from hassio:

inet6 2a02:908:3711:xxxx::43f8/128
inet6 2a02:908:3711:xxxx:ba27:ebff:fec9:8eaa/64

if I am connected to the internet via an easybox router these addresses work as I enter them in the browser

if I try to use them from a different network, for example from an o2 mobile phone, not work!
it is possible to somehow solve this problem?

NOTE:
ds-lite is ipv6 <=> mobile o2 is ipv4 Not Work!
ds-lite is ipv6 <=> other ds-lite is ipv6 Work!

Add-on Duck DNS update ipv6 not work - cause hassio docker container work in only ipv4
S o l u t i o n !
!! For DS-LITE !! H A S S I O !!
IPV6

1.Create an account on duckdns.
2.Make script sh udns.sh :

#!/bin/bash

# register a subdomain at https://www.duckdns.org/ to get your token
SUBDOMAIN="xxxxx.duckdns.org" GET From duckdns.org
TOKEN="xxxxxxxxxxxxxxxx" GET From duckdns.org
IPV6=`ip r get to 2001:4860:4860::8888 | perl -ne '/src ([\w:]+)/ && print "$1\n"'`

# no modification below needed
curl --silent "https://www.duckdns.org/update?domains=$SUBDOMAIN&token=$TOKEN&ipv6=$IPV6"
if [ $? -eq 0 ];
then
    echo "update suceeded IPV6: "
    echo $IPV6
else
    echo "update failed"
fi
  1. Install Add-on SSH & Web Terminal
  2. Put the file script udns.sh to hassio host via Samba e.g. folder /config
  3. Restart Hassio
  4. Run Add-on SSH
  5. Make Automation
- id: '1601735912110'
  alias: updateipv6
  description: Update IPV6 DuckDNS udns.sh
  trigger:
  - platform: time_pattern
    hours: '1'
  condition: []
  action:
  - service: hassio.addon_stdin
    data:
      addon: xxxxxxx_ssh                  <<<<<< id From addon documentation
      input: /root/config/udns.sh
  mode: single

NOTE:

  • Automation does not start automatically after restart!
  • Additionally, I use the add-on: Nginx Proxy Manager!

Option without SSH & Web Terminal addon

Hey, thanks for the instruction.
Where do I get the Feedback with:

then
    echo "update suceeded IPV6: "
    echo $IPV6
else
    echo "update failed"
fi

To be clear: Where is this logged to get sure it has been run with(out) problems?
