Yes, you can set it up, but not without the cooperation of your ISP, as they must delegate the names to you. If they provide a web interface to change the PTR records yourself, then you might find it easiest to simply stick with that. -- David Phillips <david at acz.org> http://david.acz.org/ _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
