One IP can't connect

    Hey!

    I have set up ISPConfig on Debian 6. Everything is working fine, but I can't connect to my server on my smartphone with 3G. I can't ping, connect to webserver/ISPConfig CP or SSH.

    When I turn on Wi-Fi on my smartphone, it all works, so I think it has to do something with the IP of my phone.

    The only thing I could find about this was fail2ban, but fail2bans tells me there are no bans active:

    Code:
    root@backbone:~# fail2ban-client status
    Status
    |- Number of jail:      3
    `- Jail list:           pureftpd, dovecot-pop3imap, ssh
    root@backbone:~# fail2ban-client status pureftpd
    Status for the jail: pureftpd
    |- filter
    |  |- File list:        /var/log/syslog
    |  |- Currently failed: 0
    |  `- Total failed:     1
    `- action
       |- Currently banned: 0
       |  `- IP list:
       `- Total banned:     0
    root@backbone:~# fail2ban-client status ssh
    Status for the jail: ssh
    |- filter
    |  |- File list:        /var/log/auth.log
    |  |- Currently failed: 0
    |  `- Total failed:     0
    `- action
       |- Currently banned: 0
       |  `- IP list:
       `- Total banned:     0
    root@backbone:~# fail2ban-client status dovecot-pop3imap
    Status for the jail: dovecot-pop3imap
    |- filter
    |  |- File list:        /var/log/mail.log
    |  |- Currently failed: 0
    |  `- Total failed:     0
    `- action
       |- Currently banned: 0
       |  `- IP list:
       `- Total banned:     0
    
    Does someone know if there is any other IP ban software in Debian/ISPConfig? Or what else it could be?

    Thanks!

    Maybe it is a routing problem of your mobile carrier.

    Hey Falko, that was exactly the problem! My carrier unblocked the IP.

    Thanks!
