Hi Jörg,
computer centre (URZ) will install WLAN, so you can at least use protocols www (http, https), ssh, pop3, imap.
Maybe, some aditional ports like 5190 for instant messangers or 389 (636) for ldap (ssl) access will be opened, too. But if you want to have access to other ports than mentioned above, better prepare for tunneling via ssh.
About WLAN-configuration parameters like (S)SID, etc. you will be informed on meeting.
Regards,
Martin
