It should be noted that the debian installer (or rather landscape-config) waits indefinitely if it doesn't manage to get a connection to the landscape server. A non-export users won't know why the installer stops doing anything.
At the very least, landscape-config (or the process calling it) should timeout with an appropriate error message after a few minutes, and the install dialog should display a warning message in the dialogue where the update strategy is displayed saying that the landscape option might not work behind a firewall (until the issue is properly fixed).
