info and a problem

["Karsten N." <tor-admin@xxxxxxxxxxxxxxxxxxxx>]

Hi,

only for information:

We have setup a new tor status page:

    https://server.privacyfoundation.de/torstatus/

an because our first tor web proxy is working hard,
we have setup a second web proxy for tor:

    https://privacybox.de/tor-proxy.en.html


And I have a problem. A friend of me is running a tor node behind a
DSL dial-in account. DynDNS setup is correct.
Yesterday the node run well, today it do not work.

He is using Debian 5.0, tor 0.2.0.34 (r18423)  (noreply-package)

Logfile:

> Tor 0.2.0.34 (r18423) opening log file.
> Your Tor server's identity key fingerprint is .....
> We now have enough directory information to build circuits.
>
> Guessed our IP address as xx.yy.88.26.

First, tor detects the correct IP of the DynDNS: xx.yy.88.26
After a short time, the IP Address has changed to: xx.yy.67.255

Why?

He checked the IP of his dial-in Account by check.torproject.org, by
showmyip.com by....  every service shows xx.yy.88.26. He connect my
server by several protocols and I can see, his IP is  xx.yy.88.26.

The nick of his node is unique. What goes wrong?
