I use aiccu-beta1-windows-gui.exe to Logon with my SixXS account/password. I selected the " behind NAT" checkbox since I am behind a firewall with my home network. After starting: nt6tunnel -vd 1119 newszilla6.xs4all.nl 119 and trying to log in on the Newszilla server with Grab-it (127.0.0.1, port 1119, no name /password) there was no connection made and the next text appears in the dos-box: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.
