REPOST: Adding FTP to YAST as Installation Source

I have 8.2 personal and want to add one of the ftp sites as an additional installation source in YAST. I did this once before, but I cannot seem to make it work now. When I fill in the relevant ftp location and directory in Add Installation Source (for example ftp.gwdg.de and /pub/linux/suse/ftp.suse.com/suse/i386/8.2) I get the following error: Unable to create installation source from URL 'ftp://ftp.gwdg.de/pub/linux/suse/ftp.suse.com/suse/i386/8.2'. Details: ERROR(InstSrc:E_no_instsrc_on_media) Any suggestions on what I need to do to make this work. TIA
