What IP addresses have you assigned to that guest, and in what order? > Thanks in advance ! -- Daniel Hokka Zakrisson -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
