How to achieve these goals on Xbian? Do You have an idea about commands and its parameters to run please?

  1. Verify that the router is properly forwarding port 12345 to the Linux xbian system.
    i know that there are online port checkers, but when i nmap or ping Tor detected public IP, it timeout, so how it can work?
  2. Check any firewalls or network configuration settings that may be blocking incoming connections to the bridge.
    here i know “iptables -S -t nat” but output is ok:
    iptables -S -t nat
    -P PREROUTING ACCEPT
    -P INPUT ACCEPT
    -P OUTPUT ACCEPT
    -P POSTROUTING ACCEPT
  3. Consider upgrading to a newer version of Tor to take advantage of bug fixes and improvements. This may also help ensure that the bridge is recognized by the directory authorities.
    https://support.torproject.org/apt/tor-deb-repo/ says “The package repository offers amd64, arm64, and i386 binaries.” but i have armhf … yet i am using older Tor version 0.4.5.10 from OS default repository. So how to install latest for my arch?
